  2. Help Cleo work out the answer.
    Discuss converting the numbers from words back into digits. Discuss that the bar model helps us to visualise what the problem is asking us but we still need to use another method to solve. Discuss suitable methods for solving such as partitioning or column method.
    54 – 39 = 15

  3. Help Blake work out the answer.
    Discuss how to use the part-whole model to help subtract the 2-digit numbers. Discuss suitable methods for subtracting with exchanging such as partitioning or column method.
