Smash and Build: Double Digit Addition and Subtraction
Regrouping finally makes sense, because learners can see exactly why it works.
How it works
Part 3 of No Panic Numbers: regrouping with a picture attached to it.
One strategy, lots of room
Each packet teaches one way to solve the problem and then gives learners enough practice to make it theirs.
Help that fades
Early pages carry more support. Later pages pull it back, so learners finish doing it on their own.
Calm pages
Plenty of white space, a few problems per page, and nothing timed.
What's inside
Using it
Go at your learner's pace, one step or one page at a time. Read the grown-up guide once and you're ready, no teaching background needed.
Run it as an intervention, a small group or independent practice. It prints clean on the school copier.
