Why is place value so hard? Place value is the understanding that the place of the digit determines its value. So a 2 in the ones place is far different from a 2 in the tens place. It is one of the most important concepts to understand in math because it is the root … Continue reading Place Value Cards for Primary
When the BC ministry re-wrote their math curriculum, everyone (well maybe only like 90%!) complained and thought what’s the big idea?! But that’s just the point...it is all about big ideas! Mathematics has often been thought of as a skill-based subject (i.e. the old curriculum); it’s not. Mathematics is a set of connected, big ideas … Continue reading Hey! What’s the BIG idea?!
With summer almost upon us, I often have parents ask: how can they keep their kids practicing math facts over the summer without having a full out rebellion on their hands?! Well, KenKen is the answer! It is a brilliant math puzzle that helps build fluency in addition and subtraction facts, as well as multiplication … Continue reading Kindies doing KenKen!
My Talk on Talking Points My new favourite technique for getting students to communicate mathematically, in a way that requires them to reason and justify their thinking, is Talking Points! Over the years, I have used different methods as a way to elicit student thinking; however, I love the way talking points encourage each child … Continue reading Three Cheers for Talking Points!
Not a box! One of my favourite books is “Not a box” by Antoinette Portis. I love it because it reminds me of my own children who refuse to let us throw out boxes. They have all these great ideas of what the boxes can be turned into and although the mess drives me nuts, I'm always … Continue reading Not-your-usual-shape Lesson!
The other day, a Grade One teacher asked me to do a demonstration lesson on ordinal numbers. She wanted to see how I would approach it. I had to think for a moment because I have never explicitly taught ordinal numbers. Usually, by the time students get to me, they’ve already learned them. I just … Continue reading Ordinal numbers are anything but ordinary!
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
You can hardly get through the week without coding appearing as a headline in the news somewhere. All the big companies are getting involved with coding initiatives and all of the governments are supporting coding with their own endeavours. Here are a few examples: “Google to Donate $190K To 'Black Girls Code' Initiative” "Microsoft Releases 'Minecraft' … Continue reading Coding for Kindergarten!
I love teaching math with stories. Not only do I value the authentic nature of solving math problems from books, I love how quickly they can engage a whole class. I find it so rewarding when a child makes the connection between the story and the math involved. I taught with a book the other … Continue reading Story time in math class!
Rory was playing the Osmo Numbers Game (he was pretty spoiled by Santa this year!), and he was getting really frustrated because the game wanted him to make the number 12, and he kept doing 1 and 2 (instead of 10 and 2) and not getting it right. This led me to wonder how I … Continue reading Digits versus Numbers
