To help us understand what happens to numbers when we multiply and divide by 10, 100 and 1000, we became a human number. We looked at columns and were introduced to the decimal point. Ellie-May was a great decimal point and took her role very seriously, making sure she didn’t move! We then looked at what would happen to our number if we multiplied or divided by 10, 100 and 1000 and how our number would move one, two or three places on our place value chart.
In maths this week we have focused on multi-step worded problems using our addition, subtraction, multiplication and division skills. In arithmetic we have also learnt squared and cubed numbers, order of operations and have continued consolidating long division. Keep up the great work Crew Mcloughlin! We are working so hard!
To consolidate our operation skills we participated in a carousel of activities. There were four stations: short division, long division, long multiplication and TTRS as we are still getting some questions incorrect because of our times tables knowledge!
Today in Crew MI, we enjoyed learning about roman numerals. We decided it was like trying to crack a code. We learnt that different letters meant different symbols and we had to put them in the right order to create our numbers. We then put this into practise a completed a task on my maths.
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:
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.
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!
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.
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.
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!
