Category 1“The following number talks consist of computation problems that begin the discussion of what happens when you remove a larger number from a smaller quantity. The number line will be an important tool to use when reasoning with this strategy.”

Example of what this strategy might look like:123 – 59 (100 + 20 + 3) – (50 – 9)100 – 0 = 10020 – 50 = -303 – 9= -6100 – 30 = 7070 – 6 = 64

Category 2“The following number talks consist of two-digit computation problems to continue the work with this strategy. A deliberate sequence is used to support thinking for the initial problem in each section. The last problem in each section allows students to test their thinking with a similar problem.”
