Mathemagicians

Year 3 and 4 Mathemagicians

Hello girls!

I hope you are all well and are finding some fun ways to spend this bizarre and unusual time. Due to the fact that we haven’t been able to have any sessions for a little while, I thought I’d send you all this with some of the Maths games we played and some of the activities we used in our sessions, along with some new ideas to help keep your Maths skills up!

Stay safe and hopefully see you all soon!

Mr. Collinge

Broken Calculators
 
Broken calculator challenges require you to find different numbers but only with the buttons you have available. Here is a link where you can set your own challenges:

 
Start with level 1 and 2 but if you want to really challenge yourself, you can go even further!
Multiple Bingo
 
Using a 3x3 grid, think of a times table. For example, if you chose the 4 times table, you should complete a grid like the one below. Ask somebody else to call out calculations, such as "3x4" or "4x4". If you have an answer, you can tick it off. Who can tick their numbers off the quickest? You could it against the clock so you have to be quick with your answers!
 
You could do this with any times tables or any sized grid!
Biased Dice
 
During the autumn term, the girls and I made biased dice. We designed the net of the die before putting it together with one small twist!
 
We discussed how opposite sides of a die add up to 7 and how we could make the die unfair to use. In order to make a number come up more frequently, we placed a piece of Blu-Tack on the opposite side to the number we wanted. For example, if we wanted to have a higher chance of rolling a six, we'd place the Blu-Tack on the inside of the face of 1.
 
From there, there is loads you can do in terms of probability, fractions, percentages and many others. I've attached a blank die net for you to use should you want to give it a go!
What's My Number?

Put a post it note on somebody’s forehead with a number between 1 and 100 on it. They are allowed to ask you questions but you are only able to answer by saying ‘yes’ or ‘no’. Questions could be ‘am I an odd/even number?’ or ‘am I in the 5 times table?’.

Magic Square
 
This works like noughts and crosses but you need to get a horiztonal, vertical or diagonal line that adds up to 15. You can only use the numbers 1 – 9 and you can only use each number once. Take alternate goes and try to stop the other person winning.

Extension – you can try a 4 x 4 square and use the numbers 1 – 16. The magic number changes from 15 to 34.

Familiar 3D Shapes
 
Below are some nets of familiar 3D shapes. We put some of them together in one of our sessions before Christmas but they might like to have another go. 
 
You will need a printer for this one!
