To activate our lesson today on fact families we built our own houses. We then used our knowledge of number bonds to learn about the four number sentences that make up a fact family.

Rounding to the nearest 1000
Crew Hamill have worked really hard this week to round numbers to the nearest 10, 100 and then 1000. We began by identifying the multiple of 10, 100 or 1000 that was before and after our number. For example, if our number was 1235, the thousand before would be 1000 and the thousand after would be 2000. We then had to decide, using a number line to support, which multiple it was closest to and therefore which number we would round it to. We then learned a rounding rhyme to help us solve this more easily:
- Find the place (which place you are rounding to)
- Look next door (look at the column to the right)
- 5 or bigger? +1 more
- 4 or less? Let it rest
Arithmetic – exchanging
In arithmetic, we have been learning about exchanging and how we need to exchange a ten for 10 ones when we don’t have enough to subtract. Children were encouraged to draw the tens and ones above their number so they could see what was happening when they exchange.
Arithmetic Superstars!
In academic crew this morning, Crew Mcloughlin have reflected on their performance in their latest arithmetic test and wow did we deserve a massive celebration! A high percentage of children have improved their score and some by a whopping 15 marks! We could not be prouder of each and every child in our Crew. The hard work is definitely paying off!
Creating 3D shapes, using 2D shapes
In magic maths we’ve been exploring the properties of shapes. We gave each other instructions to create 3D models. We had great fun collaborating.
Estimating on a number line
In maths, we continued our work on number lines. On this occasion, we had some missing number and had to estimate what the number was but also ensuring they were in order.
Number Lines
Last week, we became a human number line to help us understand the different intervals. We started quite simple so children could understand that each person went up a set amount. Once we were feeling more confident with it, we missed some numbers out and children had to work together to figure out the missing intervals.
Ordering numbers to 10,000
To consolidate our learning on ordering numbers to 10,000, we each became a 4-digit number! To begin with, we were able to choose any 4-digit number we liked but then we were given specific criteria for our numbers. For example, each digit had to have a different value. We then had to order ourselves from smallest to biggest or biggest to smallest, depending on the instruction we were given. We worked really hard to make sure that the value of the person to one side of us was bigger than us and the value of the person to the other side was smaller. We used our maths vocabulary to have a conversation about why we should be in a certain position. For example, “My tens column has a higher value so I have to bie bigger.” Shoutout to Jenson who was able to become the teacher during this lesson and instruct people where they should be going and why! To end our lesson, we were given four 4-digit numbers that we had to order from smallest to biggest on a whiteboard. Miss was very excited when we all managed to complete this independently!
TTRS in Crew Godley
We are striving to get better in our times tables, we are showing that a little bit of practice each day we are able to increase our speed and accuracy.
Rounding in MI
We continue to consolidate our place value knowledge during our do now activities. Today we ordered numbers in ascending and descending order. We then looked at a reasoning problem that we unpicked together.
The main part of our lesson looked at rounding to the nearest hundred which we did really well with. Tomorrow, Mrs Ibbotson will consolidate our learning on this before using the lesson to model some reasoning and problem solving questions. We are looking forward to working in mini crews to discuss and solve these problems.
