Maths Table Quiz 3rd/4th


The 3rd and 4th classes took part in a table quiz for maths week.

There were some fantastic mathematicians on display and they worked out some very difficult maths problems. Not to mention the boys watching on, that were eager to display their mathematical knowledge.

It was a closely fought contest between all of the teams, but it was the experience of both 4th classes that seen them battle it out to a controversial finish.

After a recount of points it was G5 that were the eventual winners.

Puzzle 3: How Old is Dave?

Fresh and invigorated after completing his algebra homework, Dave appeared at the living room door. He held a piece of paper covered in scribbled numbers, ‘m’s, ‘d’s, and equations.

“Dad!” he announced. “Five years from now you’ll be only double my age!”

“Amazing!” Dad almost looked up from the TV, but knew he hadn’t finished.

“But five years ago, you were triple my age then!”

“I suppose in another ten years we’ll be the same age,” Dad grunted, changing channels.

How old is Dave?

Puzzle 2: Missing Price!!!

When I went to the supermarket, I purchased four items. The following shows the cost of three of the items:


The queue for the checkout was pretty long, so to quench my boredom I started playing with my pocket calculator while waiting.

I found out, to my surprise, that the four prices of the four items I purchased added to the same number as I got when I multiplied the four prices together.

What was the price of the fourth item?

Puzzle 1: Grandmas & Trolls

You are on your way to visit your Grandma, who lives at the end of the valley. It’s her birthday, and you want to give her the cakes you’ve made.

Between your house and her house, you have to cross 7 bridges, and as it goes in the land of make believe, there is a troll under every bridge! Each troll, quite rightly, insists that you pay a troll toll. Before you can cross their bridge, you have to give them half of the cakes you are carrying, but as they are kind trolls, they each give you back a single cake.

How many cakes do you have to leave home with to make sure that you arrive at Grandma’s with exactly 2 cakes?
