Explain to students that you will show them a group of coins and they will estimate the total value of the coins. Tell them they will be seeing the coins from a much different perspective than usual.
Hold several coins in your hand under Twist. Adjust the focus then slowly move your hand so the students see all of the coins or, for additional challenge, part of each coin.
Have the students write an estimate of the total value of the coins on the attached sheet. 4. Show the students the coins and calculate the actual amount as a group. Students write actual amounts next to their estimates. Have students whose estimates were closest to the amount explain how they determined their answers.
Repeat the process with varying amounts and types of coins. Then have pairs of students try the activity with each other, writing estimates and actual amounts.
Use students' estimates to assess abilities to identify coins and add coin amounts.
Say aloud various coin combinations, such as nickel, dime, penny. Have students write the amounts after simply hearing the coin combinations. Check for accuracy. Or have students write the total amount of coin values shown with Twist and list other coin combinations for the same amount.
