We have been learning how to subtract. Last week we worked on exchanging tens into units. Some of us subtracted 2 digit others. Some of us challenged ourselves to subtract 3 digit numbers.

Maths: Multiplication
In maths Primary 4 have been working on our new focus, multiplication. We looking at the 3,6 and 9 tables in particular but still thinking about other tables!
We are learning that multiplication is easy when you practice and that division is just multiplication backwards!
Primary 4 have been working so hard on this, and we have all been trying to practice as much as possible at home!
There are some good game links on multiplication practice (all tables), Hit the Button (focuses on quick fire questions) and general practice sites, games and challenges.
Here we are working hard…
Maths New Topic: Time
Primary 4’s new topic in maths is time. We have been working really hard on understanding how to read a clock, and to know when it is o’clock, quarter past, half past and quarter to. We have been playing some great time games and we made little mini clocks which help us ‘see’ the time. We have also been ‘making’ the time using our bodies like clocks. Check out our fab photos below!
Time app for iPad: Telling the Time
There are some great time games on this site.

2D Shape
We are learning about 2D shape this term with Mrs McIntyre. We have been tiling with squares, triangles, hexagons and rectangles.
Here is a link to some tiling online – Tiling
Here is a link to an some art work we looked at to inspire our Art work – Escher’s art
For next week, Mrs McIntyre has put a wordbank of shapes on the Maths wall – we have to see how many of them we can name. The shapes are – quadrilateral, rhombus, kite, nonagon, decagon, heptagon,trapezium and octagon.
What can you find out for next week?
Pictures will be added soon.
Coin Multiplication – Peer Teaching
Today we were doing our CLIC challenges. P4 were having trouble with the sum 48×7. Primary 5 realised that they knew a strategy called Coin Multiplication which would help them to do this sum.
Primary 5 taught P4 how to make the grid and then how to do coin multiplication. First of they showed the whole class and then they worked with 2 P4s to help them with some new grids.
Look at our photos.
Carmen thought it was good to have someone different from the teacher showing her something new.
Aimee thought that the P4s picked up the strategy quite quickly and it was easy to teach her peers.
Lorna thought that coin multiplication is much easier than doing it in your head as you have a grid to help you.images (1)
