Encourage students to share their strategies for solving the addition problems.

  1. 134 jumps; student strategies will vary. Some students may use their 200 Chart and others may use invented strategies or a strategy from the Addition Strategies Menu. Encourage students who use different strategies to share.
    1. 20¢
    2. 40¢
    3. $2.00
    4. Possible response: I know 100 cents is the same as one dollar, so I added 100 + 100 = 200 or $2.00.
