Do All Fractions Fit on a Number Line?

• Learn something NEW…….. preferably about fractions.

• Leave curious about what the new standards expect in terms of fractions instruction.

How can I cut the brownie so that two people can have equal shares?

Please fold into the following equal pieces

Label each piece with the fraction name

• 4 equal pieces

• 8 equal pieces

• 3 equal pieces

• 6 equal pieces

Cut apart each equal piece

Order these unit fractions from smallest to largest with the smallest over to the left and the largest over to the right.

• Use a sticky note to represent the whole numbers on your number line?

• Shuffle fractions cards

• Turn over 5 fractions cards (not using percents)

• Determine with your group where you would place these numbers on your number line.

• After 1st round, turn over 10 cards

For each fraction pair find 3 fractions using at least 2 different strategies

⅛ and ¼

¼ and⅕

¼ and ⅓

• Only 24% knew that there was an infinite amount of numbers between ¼ and ⅕.

• 43% claimed that there are no numbers between ¼ and ⅕ and

• 30% claimed that ⅕ is the successor to ¼

Aunt Sally has a jar that holds one cup of liquid. Her salad dressing recipe calls for 2/3 cup of oil, 1/8 cup of vinegar, and 1/4 cup of juice.

Is the jar large enough to hold all the oil, vinegar, and juice?

Give a rough estimate of the values represented by points A and B on the number lines below.

By comparing fractions, students come to understand them as something more—numbers that have magnitude.

Density – between any two rational numbers we can find a third rational number. This property leads to the fact that between any two rational numbers, no matter how close, there are infinitely many other rational numbers.
