Find the value of each expression mentally.

Andre, Lin, and Clare will represent on a number line.

• Andre says, “Oh, no! We’ll need to partition the line into 100 equal parts and count 70 parts just to mark one point!”
• Lin says, “What if we mark instead? We could partition the line into just 10 parts and count 7 parts.”
• Clare says, “What if we partition the line into 5 parts and mark ?”

Do you agree with any of them? Explain or show your reasoning.

Around the room you will find 6 posters, each showing either 2 or 3 fractions.

With your group, visit at least 2 posters: one with 2 fractions and one with 3 fractions.

For the poster with 2 fractions:

• Explain or show how you know the fractions are equivalent.
• Write a new equivalent fraction on a sticky note and add it to the poster. Try to find a fraction that hasn’t already been written by someone else.

  We visited poster __________, which shows __________ and __________.

  New equivalent fraction: __________

For the poster with 3 fractions:

• Identify 2 fractions that are equivalent. Explain your reasoning.

  We visited poster __________, which shows __________, __________, and __________.

  __________ and __________ are equivalent fractions.
