I went and asked a few Grade 5 students to tell me about odd and even numbers, and this is what they said: Student A: “3 is odd, 2 is even” Student B:“anything ending in a 0, 2,4,6,8 is even and anything ending in a 1, 3, 5, 7, 9” is odd. The students told … Continue reading Odds and Evens

What the heck is a rekenrek?
Never heard of a rekenrek? You’re not alone, but I’m here to tell you, it is one of the best manipulatives for developing number sense in early primary, and you can make it yourself!

The Facts about Facts!
Why bother?! In this age of technology, do we still need to learn number facts? Absolutely! Thinking flexibly about numbers opens up thinking for more complex mathematical problems.

For example, Rory used to say he wanted a hangaber for dinner. Alan and I thought it was adorable, and did nothing to encourage the proper pronunciation of the … Continue reading Sorting and grouping

Manipulatives are models that help children think and reflect on new ideas in math. They include resources that allow children to explore, question, guess and check, but more importantly, to play with the … Continue reading Making Math Meaningful with Manipulatives!
Learning to count…baby steps.
Oliver is 2 ½ and quite pleased with his ability to count. He can count forwards and backwards (and sometimes correctly!), but he has no understanding of what the numbers mean, although he does know that numbers relate to quantity. Rory on the other hand is 4 ½ and he can count correctly and accurately … Continue reading Learning to count…baby steps.
