Math games – math puzzles, or card and board games can show that math is fun. They also require trial and error thinking, enhance numeracy and logical thinking, and promote discussion.
Math in digital games – if your child enjoys using technology, introduce them to fun and educational online games and activities.
Math at the grocery store – talk to your child about how to weigh items on a scale or how to estimate the total bill as you fill your cart.
