Welcome to Santan Parent Math Night! First Grade Mathematics Instruction and Strategies
Tonight’s Objectives • Overview of Math Tools • Overview of Math Strategies • Key Vocabulary Your Child Should Know (by the end of the year) • Questions from Parents
First Grade Math Tools • In first grade, your child will be introduced and expected to use a variety of math tools to help problem solve. • These tools are helpful in making concrete meaning to abstract concepts. Students need to be able to fundamentally understand what the concepts and skills are before asked to solve it in a problem-format (more abstract). • Example: 10 more/10 less with Base-Ten blocks v. Just knowing it by adding/subtracting.
First Grade Math Tools • Number Lines • Base Ten Blocks • Tens Frames (and Five Frames) • Hundred’s Charts • Tallies • Place Value Mats • White Boards/Markers • Math Notebooks • Fingers • Here are examples of some of the most used tools at our grade level: • Manipulatives (including unifex cubes, linkers, dominos, dice, number cubes, counters, double-sided counters, tiles, etc.)
First Grade Math Strategies • We teach the students that strategies are the plan to help solve the problem. Students are expected to know what strategy he/she used, and also be able to explain that to a peer. • Although there are many problem-solving strategies, most of the focus in first grade will be focused on number sense—more specifically with addition and subtraction strategies.
First Grade Math Strategies • Creating an Easier Known Sum • Creating an Easier Known Difference • Creating Carrots (Looking at Place Value) • Decomposing Numbers • Think Addition (Fact Families) • Plus Zero/Minus Zero • Counting Up • Counting Back • Doubles • Doubles Plus (1, 2, 3) • Doubles Minus (1, 2, 3) • Tens Partners • Plus Ten/Minus Ten • A Number Minus Itself
Key Vocabulary • Students will learn specific math vocabulary that will carry on with them through the grade-levels. • It is important they learn the correct words and what they mean initially, rather than learning a simpler term that they will have to re-learn later on. • Math Notebooks
Key Vocabulary • Equal (Equal to) • Equivalent • Equation/Number Sentence • Symbol • Quantity • Greater than/More than • Less than • Strategy • Tool • Place Value • Units, Rods, Flats (ones, tens, hundreds) • Addition • Plus • Sum • Addend • Compose • Subtraction • Minus (take away) • Minuend • Subtrahend • Difference • Decompose
Questions? • Thank you for coming tonight! • This presentation will be posted on our website for future review. • You can also email your child’s teacher with any questions at any time if you need help working on math with your child at home.
