My son loves playing around with numbers and he adores counting things. We recently read a book about skip counting and he decided he wanted to spend some time playing around with counters.
Coins are a fabulous tool for skip counting activities. I have a ton of pennies so they were the perfect manipulative for our recent math activity. I cut little squares of paper and labeled each with multiples of five. 5, 10, 15, etc. so he could practice skip counting by 5s. Kiddo counted out the pennies for each number.
Being the number-lover that he is, this was great fun for him. He also did variations, such as taking away the squares with 5s on them (5, 15, 25, etc) and counting only by tens.
He cracks me up because he demanded that I ask him math questions, so I asked things like “If you had two groups of 10 and added 1 more group of 10, how many would you have?” etc. For each question, he would manipulate the pennies if he needed help to figure out the answer.
This went on for quite a while… but he also just liked playing with the pennies by himself, too.
