T.i.P.S.

For this standard, students are using concrete models to represent integer operations and also to then connect those models to algorithms. Integers give the increased challenge of working with negative numbers as well, so the most useful tools here would be twocolor counters and the use of number lines for certain operations.
For example, if the expression is asking students to subtract 2 from 4, written as 4 – (2), students should not just memorize rules about positives and negatives. Instead, they could use a number line and look for the distance between the two numbers (which is 6). Students would then connect this back to the algorithm use to solve the expression, and see that subtraction means difference, and we would use that distance to solve.
