1. Write story problems using the same two numbers that model: (a) comparison subtraction (b) take-away subtraction (c) missing addend
2. Analyze student’s thinking to determine if the solution steps make sense and provide the correct solution when the student is using a non-traditional method for subtraction or addition. (Look at the student work on page 74.)
3. Make sketches that illustrate the solution process for multiplication whole numbers with fractions. (i.e., ¼ x 12 and 12 x ¼)
4. Work with place value to break down numbers in unconventional parts. i.e. find the number that has 11 tens, 12 ones, and 13 hundredths.
5. Division can be modeled using either Equal Share or Repeated Subtraction. If students are to use base-ten blocks to model their solution process, explain what numbers work best for each model and why.
6. Be able to write word problems that model Equal Share and Repeated Subtraction.
