Five ways to find an answer without counting. Tap one, then press Show me to go a step at a time.
How many empty squares are left?
7 + ? = 10Do not count back. Ask what you add to get there.
13 − 8Use a double you already know, then add the extra one.
7 + 8Fill the first frame to ten, then add what is left.
9 + 6Land on ten first, then take the rest.
15 − 7Any numbers work. Add them to the address, for example
show-me.html?m=make-ten&a=8&b=7, and &s=3 opens it at step 3.
