Building Math Confidence

Ann-Marie Hunter

- Math skills are often seen as a source of anxiety; students are sometimes made to feel that they are destined to fail.
- Your efforts to reduce Math anxiety can alter their attitudes towards their own abilities and create success for students.

- Connecting to the learners in your classroom is one of the most important aspects of teaching – it conveys to the learners that they can trust you and that you believe they can succeed.
- Focussing on creating a learning environment that is meaningful to the learner, allowing him/her to explore topics with confidence, supports the creation of a positive learning environment. You can use Math teaching to reach this goal!

Words of Wisdom

“I had a great feeling of relief when I began to understand that a youngster needs more than just subject matter.

Oh, I know mathematics well, and I teach it well. I used to think that that was all I needed to do.

Now I teach children, not math. I accept the fact that I can only succeed partially with some of them.

I have found further that my own personhood has educatable value. When I don’t have to know all the answers I seem to have more answers than before, when I tried to be the expert.

The youngster who really made me understand this was Eddie. I asked him one day why he thought he was doing so much better than last year.

He gave meaning to my whole new orientation. “It’s because I like myself now when I’m with you,” he said.”

~ a quote from a teacher

- Brain research - how it can sharpen your teaching
- 8 critical Topics and Strategies:
- Problem solving Word Questions
- Place value
- Focus on the Facts
- Mental Math & Estimating
- Fractions & Decimals
- Mastering the Basics – Power of Ten
- Geometry & Measurement
- Games and tricks
- Additional strategies to enhance your Math instruction
- Building your own math confidence

- Semantic memory
- People can say “The Earth is the third planet from the sun”, without having any specific experience in going to space to see that the Earth is in that position.

- Episodic memory
- A person may remember a recent trip to Paris, mentally reliving events that happened there, in the mind’s eye seeing again the places visited, sights seen, sounds heard, aromas smelled, and people met.

- Procedural memory
- Driving a standard vehicle or riding a bike is an example of use of procedural memory.

- Personalize instruction to promote retention
- Use visual tools for learning
- Verbally reinforce learning as much as possible
- Use hands-on materials as much as possible
- Incorporate movement within each lesson

1) Problem Solving – Word Questions*Chooseactivities to help students feel empowered to think aloud and share ideas with others in solving word questions. *Use word questions that have more than one answer.

If Joe and his brother were playing basketball outside and Joe took three times as many shots as his brother, how many shots could Joe have taken if they took no more than 40 shots in total.

- sum - the answer when you add numbers.
- difference - the answer when you subtract numbers.
- product- the answer when you multiply numbers.
- quotient - the answer when you divide numbers.
- total - the amount that is gained by the addition of smaller amounts.

- factor – an integer you can multiply times a number to get
another number

Example: 3 is a factor of 6 because 3 X 2 = 6.

And because 3 X 2 = 6, 2 is another factor of 6!

- multiple- the result of multiplying a number by an integer
Example: You can identify a multiple of 4 by multiplying 4 by 2.

4 X 2 = 8 makes 8 a multiple of 4.

Another multiple of 4 is 12, since 4 X 3 = 12.

2) Have students create word questions BEFORE they are asked to answer textbook questions.

Give choices in their word question challenge

Example:

- Word Question Criteria:
- Use decimal numbers or fractions in your question.
- Use numbers that are either less than 20 or more than 50.
- Ensure that there is more than one correct answer to your question.

- Get Started - Record important details in an organized fashion
- Use a Diagram to represent the parts of the question
- Make the question Simpler using Easier Numbers
- Get Unstuck – try a different approach

This is where the word question is written.

Post finished Place Mats to celebrate diversity of solutions.

____ “hundred” ____ “tee” ____ then say the final digit.

Example: 572 reads as: 5 hundred, 7 tee, two.

Read any number:

__ __ __ MILLION __ __ __THOUSAND __ __ __ . __ tenths

and

__ __ __ MILLION __ __ __THOUSAND __ __ __ . __ __ hundredths

and

- 67 893 542
Sixty-seven MILLION,

eight hundred ninety-three THOUSAND,

five hundred forty-two

- “After learning to read, learning the multiplication facts is probably one of the most important things we learn in elementary school.” - Trevor Calkins
- We sometimes do not give the needed attention to this part of Math instruction, thinking that “we have all those units to cover!”

- The truth is that helping a child to learn and understand the basic facts is one of the best ways to build confidence!
- After he/she knows the facts, everything seems easier – and IS easier! His/her Mental Math skills begin to develop.
- Knowing Math facts allows students to confidently engage in learning new concepts.

- Ensure that students can add and subtract numbers using a visual tool – Power of Ten cards are so valuable in developing these vital skills.
- Ex: 7 + 8 = (5 + 2) + (5 + 3),
= (5 + 5) + (2 + 3),

= 10 + 5,

= 15 Let’s Try This!

Eventually, they will ‘see’ these relationships in their heads without using the cards.

Use Visual Tools to reinforce the meaning of multiplication and division:

- Power of Ten multiples sheet – visually shows groups of numbers Look in your handout for this page!

6 X 7 = 5, 10, 15, 20, 25, 30(skip counting the first columns)

(adding on the twos) 32, 34, 36, 38, 40, 42

Cross lines:Arrays:

Count the intersections. Shade a section of graph paper.

3 X 9 = 27 3 X 7 = 21

Record the total for each line. Record the total for each row.

Talk about multiples as ‘groups of #’ – to encourage the visual

3 X 2 means 3 groups of 2:

Talk about multiplication and division together – Fact Families

4 X 7 = 28,

so 7 X 4 = 28,

28/7 = 4,

and 28/4 = 7

- Visually looks like half as many to learn
- Helps students to practise what they know in an organized manner
- Use the blank sheet on one side, with answers on the other, to encourage pairs of students to study together
- Teach Perfect Squares: 2 X 2, 3 X 3, 4 X 4 … and other patterns on the sheet

- Given the answer (24), the students are challenged to find all the ‘questions’ – the factor pairs
- Students can first list all the numbers that divide evenly into the number - use divisibility rules
- 1, 2, 3, 4, 6, 8, 12, 24
- Then use ‘RAINBOWS’ to link
1 X 24 up the pairs:

2 X 12

3 X 8 Let’s practise this!

4 X 6

- A number is evenly divisible by:
- 2, if the number ends in a 0, 2, 4, 6, or 8 (the number is an even number)
- 3, if the digital sum is a 3, 6 or 9 (add all the digits of the number to get the digital sum)
- 5, if the last digit of the number is a 5 or a 0

40 000 divided by 10 000

1 + 1 + 1 + 1

9.5 – 4.1 – 1.4

8 - 4

16/4

½ + ½ + ½ + ½ + ½ + ½ + ½ + ½

300 - 296

(2 X 7) – (5 + 5)

- This aspect of your Math instruction cannot be overestimated!
- You are doing your students such a tremendous service by focussing on learning facts in a meaningful way and ensuring that they have solid knowledge of the facts when they leave your classroom.

Timestables the Fun Way! - Judy Rodriguez

- Contextual representation of
the multiplication facts.

Example 1:

- Sean climbs to the top of the hill to fly his kite.
- He’s so happy when he turns 16 and gets his driver’s license,
- because then he can drive his 4 X 4 to the top of the hill.
- Remember: You need to be 16 to drive a 4 X 4, so
4 X 4 = 16!

Example 2: 6 X 6 – Oasis in a desert.

- Model Mental Math: Talk about how you do calculations in your head, without writing anything on paper – ask students to share their methods of doing the same.
- Encourage the use of visual tools to support Mental Math. Share how the students’ thinking will improve when they can ‘see’ the numbers in their heads.

- Use Vertical Number Lines to aid in Visualizing closest ten, hundred, whole number (decimal vertical number line).
- Check your handout!
- Estimation allows students to be able to predict the approximate answer before using the calculator.
- Canada’s recent phasing out of the use of pennies is a real life situation requiring rounding to the nearest 5.

- 3 X 10 = 30
- 7 X 100 = 700
- 2 X 1000 = 2 000
- 40 X 300 = (4 X 3) = 12 then place the number of zeros in the question (3 zeros) behind the 12 to get 12 000.
- 200 X 500 = (2 X 5) = 10, then place the 4 zeros behind the 10. Answer: 100 000
- Partners challenge each other and check answers on calculators.

1) Multiplying any 2-digit number by 11:

Multiply the first digit times one higher and finish the number with ‘25’

Example: To square 75 (finding 75 X 75)

Use ‘7’, and multiply 7 X (7 + 1) = 7 X 8 = 56, then place ‘25’ on the end: 5625. 75 X 75 = 5625

- 46 + 36 = (40 + 30 = 70), (6 + 6 = 12), so the answer is 70 + 12, which is (70 + 10) + 2, or = 80 + 2 = 82
- 95 – 33 = (90 – 30) + (5 – 3)
= 60 + 2 = 62 Let’s Try This

- Encourage students to share their own methods for using Mental Math

- 25 X 32 = (25 X 30) + (25 X 2) =
- = (25 X 3 X 10) + 50
- = (75 X 10) + 50
- = 750 + 50 = 800
- Encourage students to share their own methods
Let’s try this!

- Relate fractions to decimals from the very beginning, using language: 0.23 = 23 hundredths = 23/100
- Find examples of ‘parts of a whole’ everywhere – all through the year.
- Label parts of fractions with words: #of girls = 15
#of students 27

- Use a Visual Tool for ordering Fractions
01/4 1/2 3/4 1

0.0 0.25 0.5 0.75 1.0

(Check your handout)

- The Family Math Fraction Kit is a wonderful game – I suggest that it be played with decimal names included.
- Ratios and Percent will be an easy transition from this understanding.
- Use Factoring skills to develop confidence with writing equivalent fractions and simplifying fractions.
Let’s Try This!

= 53 hundredths = 53 %

- Benefits of using the Mastering the Basics program
- Strategies for running the program successfully

- Use measurement often throughout year
- Discuss polygons and their names
- Build Geometric 3-D figures
- Classify triangles and quadrilaterals
- ‘Regular’ polygons - equal side lengths
- Use terms: Perimeter, Area, and Volume and the related Measurement skills throughout the year

- Use specific definitions:
- Perimeter: distance along the outline of a figure
- Area: number of square units inside the outline of a figure
- Volume: space inside a solid
- Clarify units used for each of these measurements

- Hands-on recording of length
- Visual tool for Metric Conversion (Check handout).
- Clarify the difference between prisms and pyramids
(Check handout)

- You cannot overestimate the power of play!
- Uses Episodic Memory
- Journals enrich learning
- Family Math Games are great!
- Power of Ten games – super!
