Geometry

This week Robins have been recapping their knowledge of geometry.

We have looked at quadrilaterals, triangles, polygons, and lines of symmetry.

Mr Lo showed us how we can review our knowledge using the tools on PurpleMash!

Active Maths: Angles and Turns

Today we did Maths in the hall. We made use of the space to recap our knowledge on 1/4 turns , 1/2 turns, clockwise and anti-clockwise.

We then worked in pairs to demonstrate our knowledge of turns. Mr Lo then asked us to discover angles on the floor and the type of angles we could see. Some of us said they were 90-degree angles, others said they were right-angles. Well done!

Finally we combined computing and maths. We were human beebots trying to follow the tracks on the floor!

Maths Workshop

This morning we had a wonderful time showing our adults our learning.

The workshop included sharing information about how we learn Maths at Bells Farm, importance of mental arithmetic, the Multiplication Times Table Check and how we can review our learning at home.

For those of you who couldn’t attend below are links to the resources.

Multiplications – 3x 6x 9x

This week in Maths we have been learning our 3, 6 and 9 times tables. Multiplication facts are really useful for helping us prepare for our understanding of doubling, halving, fractions and decimals.

Mr Lo was very impressed with everyone’s concentration.

How many do you already know?!

At the beginning of the week, Mr Lo showed how pupils in China use their knowledge of multiplications being commutative (e.g 6×3 is the same as 3 x 6) to cut down the number of times tables to recall. (And Rocking Robins are already experts on understanding commutative multiplications ,Inverse operations! ( 3×9 = 27 so I know 27 ÷9 = 3) and fact families (3×9 = 27, 9 x 3 = 27 27÷9=3 27÷3 =9)

The idea is you keep track of the times tables you can recall within 6 seconds by colouring it in. Only colour in the times table if you can recall it within 6 seconds every time!

We also looked at how the 6x table can be worked out by doubling the 3x table

or by using the 5x table + the 1x table!

For example how can we work out 6×6?

Well we can say 3×6 = 18. so 6×6 = 18 + 18 = 36

Or we might say 5×6 = 30 so 6X6 =30+ 6 = 36!

What is Area?

Robins are learning about Area this week. They have been discussing how area is the space inside a 2d shape and have explored area using post it notes.

Later this week we will be looking at strategies to calculate the area of rectilinear figures.
