Dragon Maths Challenge – Estimation

What could this be?

On Wednesday, we were all very excited to find the Dragon had left us another letter and a present!

In his letter, the dragon told us that he had heard that we are learning about measurement in maths, and that he wanted to set us a challenge.

He sent us some sheets of paper with an outline of the Giant’s hand. In the bags were magic beans.

First, we had to ESTIMATE how many beans would fit on the Giant’s palm (we knew from our Halloween maths that an estimate is a sensible guess). We had to write down our estimates in pen so we could not change them later!

Then we arranged our magic beans on the Giant’s palm to find out the actual number. Finally, we worked out the difference between our estimates and the actual number, using our calculators.

After that, we drew the outline of our own hand on the Giant’s and did the same again, only for our hand this time.

We really enjoyed the Dragon’s challenge and hope he will send us some more.

Odd and Even

On the IWB

We are learning to count in 2’s and about odd and even numbers.

On Thursday we did a maths investigation to work out odd and even numbers for ourselves. Mr Stewart gave us a number and we had to make “friends of 2” with our cubes to make our number. We discovered that if we could mke the number with groups of 2 then it was an even number and if we had one left over then we had an odd number.

Here we are hard at work.

Pleased with our work.

Monster Problem Solving

Trying out our monster faces!

We are using our problem solving skills to work out the solution to maths stories.

Today we tried work out the answer to a story about different coloured monsters. We are going to start a maths vocabulary wall. Today, Mrs Stewart wanted us to remember that the word “equal” can mean the same quantity or amount.
