Hop an addition:
Write or lay the numbers 1-10 on the floor.
Children hop the summands, by starting on the first number and then moving forward according to the second number:
e.g. 2+5: they start on the 2, hop forward 5 times and look at which number they are standing on (= 7).
Analogous, but in the other direction: 7 – 5 = 2
Kids start number on 7, make 5 hops and land on the 2
