Parent sessions and Maths Week activities


A big thank you to the parents who came along to our Maths Education sessions this week to find out about our maths programme and ways to support learning at home.


Please click on this link which will take you to a Google folder where you can find some of the resources we shared.


The students have also had a great time this week with pop-up maths challenges around the school, daily estimation challenges and lots of problem solving activities. A huge thank you to all of the teachers, especially Mrs Franks and Mrs Sharman for making maths so much fun in our school.

Amazing Seahorses



What do dogs, tigers, skunks, and dolphins have in common? They all have tails. Most tails are round: if you looked at the tail head-on from the tip, you'd see a circle (its "cross-section"). 

But the seahorse's tail is square. It's actually a stack of 36 square plates, like the bumps in your spine; each square is made up of 4 L-shaped bones. Scientists were so curious about the square tail that they made a plastic model of it to study. They figured out that a square tail is actually stronger than a round one, making it better for grabbing onto sea grasses and other things. The squares also snap back into place faster, so it takes less energy to move the tail. Scientists think this could help them build stronger robots, in case those robots ever need to grab some seaweed for dinner.


Starting out: How many sides does a square have?

Challenge 1: Seahorses swim really slowly, only about 1.5 metres per hour! Take 5 slow steps and count them starting with the number 4. What numbers do you say?  

Challenge 2: Seahorses can be as long as 35cm. If your pet seahorse is just 1cm shorter than that, how long is it? How does that compare to your hand? 

Challenge 3: A mama seahorse can lay up to 1,500 eggs at a time. If she's laid 1,100 so far, how many more could she lay?  

Challenge 4: If every 4th tail plate of the 36 (starting with the 4th) has a pink L in it, and every 6th plate starting with the 6th has a blue one, what's the first plate that has both?

Answers to this week's problems will be posted next week along with a new problem. Enjoy!
