Happy Fall!

I wanted to send along a **list of ****spooky books** **for math investigations** for spreading the Hallowe’en math love. I hope you can find some or all of these in your school libraries… There are so many fun contexts to explore around this season – from notions of pumpkin circumference to skip counting, from growing patterns to playing with the operations and the complements of 5 and 10.

One of my favourite contexts for thinking about parts of 5 stems from a story called **Room on the Broom**. Just this week I worked in a K/1 classroom and explored the missing part – or complement – of 5. Then we read the book by Julia Donaldson, in which a witch and her friends fly about on a broomstick – adding a friend until there are 5 on the broomstick in all. **We “built” some of the book’s illustrations in egg carton 5-frames, and talked about how much room was still left on our broom**, if our brooms, like hers, had 5 seats.

Next, I whispered a number from 1-4 in each child’s ear (I left off zero and five for this initial exploration…) and had them build that number in their 5-frame broomstick. Then I asked the children “How much room is on your broom?”. **The K/1 kids then had to find the person whose broom “completed” their’s**… Click to take a look in the pictures below:

**a child with 2 on his broom finds a child with three on her broom:**

3 and 2

**and they put their brooms together (one on top of the other) to fill it up.**

The egg cartons I like best are clear plastic ones – and you can see why… looking through one 5-frame to the other is a powerful way to see the parts of 5!

After a couple of turns with this game, I asked children to **record what they did** and how they filled up the room on their broom with their partner. You are welcome to use the **There’s More Room on my Broom! line master** to try this with your students as well. In this photo, you can see see one of the grade 1 students working to show her thinking on the form…

Have a fun and spooky mathy season!

Dear Carole,

I wondered if you would allow me to add a link to your site, recommending “mindfull” as a valuable learning resource (under the Page Heading- Recommended Teacher Websites)? I have an edublog,

I have attended your amazing workshops (recently retired Coquitlam teacher) and I appreciate your wisdom!

Sincerely,

Hi Carole,

Loved your workshop in Langley on Friday. Bought the Room on the Broom book on weekend.

Remember you also had partner cards — students show their number and then had to find the partner to their number. Do you have a PDF of these partner cards that could be downloaded/printed?

Thanks,

Leanne Heinrichs
