If you're a primary teacher, you'll know what I'm talking about!! Teen numbers are those ending in teen. They are often confused with -ty numbers such as twenty, thirty, etc. Oliver is pretty proud of the fact that he can count to 110 and beyond (we stopped him in the interest of time!)! However, we’d … Continue reading Teen versus Ty numbers
Counting
Fortune-tellers for learning!
Oliver’s teacher e-mailed the other day and said that Oliver needed to practice colouring at home. We had known for a while that Oliver had trouble with penmanship and so we had spent the summer getting him to practice holding a writing utensil. Our cottage was flooded with connect the dots sheets, mazes, and pre-school … Continue reading Fortune-tellers for learning!
Mastering the Pre-K Milestones
THE WHAT: If you are an early years teacher or parent, there are four milestones that you should be eagerly waiting for: Counting rotely The ability to recite an ordered number list, and not necessarily with any understanding! (See here for more: Learning to count…baby steps.) One to one correspondence The ability to pair an object in … Continue reading Mastering the Pre-K Milestones
Never heard of Numicon?!
Never heard of Numicon? You’re not alone! But ever since I introduced them to our school, my love for them has grown! Numicon are number plates that represent the numbers 1-10. They are a great manipulative for the Pre-K to Grade 2 population, in that they are large, easy to grasp and manipulate, colourful and … Continue reading Never heard of Numicon?!
Establishing Benchmarks of 5 and 10 through estimation
Much of primary math is about establishing benchmarks of 5 and 10, but have you ever stopped to wonder why those are good numbers to use? Here are a few reasons: Benchmarks of 5: We have 5 fingers (if we count the thumb!) on each hand, so a hand-y (ha!) benchmark to start with is … Continue reading Establishing Benchmarks of 5 and 10 through estimation
Odds and Evens
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! Originally developed in Holland, it looks like a mini-abacus, but functions quite differently. Although you can have many rows in a rekenrek, … Continue reading What the heck is a rekenrek?
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. Mental math is also a survival mechanism when you are out in the real-world! Think of how often you use it: How many km am I going … Continue reading The Facts about Facts!
The Importance of Place Value in Primary
The importance of place value I always start the school year with number sense. Why? Because it gives me a good indication of each student’s comfort with numbers. Number sense is the one strand that is always interwoven into other strands in mathematics. It is also the most telling predictor of a child’s success in … Continue reading The Importance of Place Value in Primary
Tenzi Frenzy!
We are away for the summer at a cottage, with no internet or TV, which I usually love. We’ve already read lots of books, frolicked in the waves, swam to the Big Rock, sailed to Seagull Island, canoed...dumped the canoe and had lots of good old fashioned fun; but my heart still felt the pitter-patter … Continue reading Tenzi Frenzy!
