Mental Stretch: Mental Math Chain

Mental Stretch: Mental Math Chain is a Grades 3–4 whole-class routine where students carry one number through a sequence of operations entirely in their heads. The teacher starts with a simple whole number, then gives a chain of multiplication, division, addition, and subtraction steps chosen so the intermediate results stay manageable. Students must maintain the running value from one instruction to the next.

Use it as a short warm-up when you want mental computation, attention, and operation fluency in the same activity. Revealing the final answer gives the class a quick check, while retracing the chain can help locate where an error occurred.
