I’m an Oxbridge educated mathematician. I love maths. It is my favourite thing.
I am really not a fan of Kumon. Kumon takes something beautiful (maths) and makes it dull and repetitive. Maths is joyous - children should be taught that maths is joyous.
Mathsy things I did at home with my kids.(Note - mine are teens now so I struggle to remember what age I did things at someone of these will be too easy and some too hard.)
Tipping out a box of raisins. Counting them. Eating one. Counting again. Repeat until all gone. Occasionally get greedy and eat lots and see what happens!
Climbing stairs whilst “counting and stomping”. We always counted. We always stomped. When counting got too easy we counted (and stomped) in 2s, 3s and 5s. (I refuse to confirm or deny whether I personally sometimes like to count in 13s, 17s or 19s when I climb stairs alone now.)
Board games. Lots and lots of board games. Especially ones with a dice. I worship Orchid toys.
House numbers. My husband’s face when out walking with dd when she was about 3 and she suddenly said “Yay! This is the odds and evens road!” (Most roads in our city count up one way and down the other.) My husband is not a mathematician.
Card games. This is at least partly my dad. He is mad on cards. Pack of cards and a cribbage board. Take it in turns to turn over a card and count it along the board. See who wins. And then slowly make the game more complex. Dd could play a decent game of cribbage before she started school. (Hey - it could be worse - it could have been poker!)
Grains of rice. We used to make patterns with rice. Different piles going up in different patterns. You can dye rice really easily so that also made it more fun.
Number patterns. 9 times table on your hands. Multiply 2 digit numbers by 11.
We also used to have a scorch mark on our microwave from an experiment we did to calculate the length of microwaves. I wouldn’t necessarily recommend that one (although it is super fun!) if you don’t want to risk burning your house down. That one was dh’s idea though - not mine. (He is a scientist!)
