My wife used a watermelon to teach math and much more fist second
If I can remember
Weight the watermelon …learn pounds and ounces
Cut the watermelon …it is a circle
Cut it in half and then quarters
Each kid gets the for quarters to make half and then a circle
They eat the watermelon saving the seeds
Put the seeds in sets of tens and the ones that are left and get the answer
There was more but I cannot remember
She taught with matchbox cars and track
She must have been a wonderful teacher.
