This week in Maths we have been using column addition to add two digit and three digit numbers. We started the week by adding numbers that didn’t bridge (e.g. 23 + 35). We carefully laid our work out using the squares in our books to help us understand the place value of each digit. During the week, we moved on to bridging ones and tens.
This week in Topic we gathered lots of descriptive vocabulary about Litterbug Doug and then used these to help us write a character description for him using lots of adjectives and adverbs. After this, we created actions and a story map for the story. Finally, we planned and wrote our very own version of Michael Recycle and Litterbug Doug. We innovated the story and changed the setting and Doug’s animal friend.
This week in topic we became scientists. We planned our own investigation to help us answer the question ‘Which of our magnets is the strongest?’ We had to decide on our equipment and our method whilst also ensuring our investigation was a fair test. After this, we completed a second science investigation where we looked at which materials have the most friction. We used toy cars on different material ramps to investigate where there was more friction. We finished the week by reading the beginning of a new story called ‘Michael Recycle and Litterbug Doug.’ We made predictions about how we thought the story would end and then acted these out. Finally, we thought of lots of descriptive language and created a Role on the Wall for Litterbug Doug.
We started the week by recapping the round and adjust strategy to add. For example: 23 + 9 = 23 + 10 – 1. We drew numberlines to help us solve these problems. We also recapped that we could use this strategy to add 8 (e.g. 23 + 8 = 23 + 10 – 2).
When we were secure with this, we moved on to using the round and adjust strategy to subtract. (e.g. 23 – 9 = 23 – 10 + 1) We used the bead strings to help us to understand why we needed to add one back on.
We have had a fantastic start to our new half term. The children have all been so well behaved and engaged with our new learning which has been super to see.
In our new Topic lessons we have had great fun experimenting and finding out about magnets and the important part they play in the world, particularly how magnets are used to help sort recycling materials so they can be reused. We learned that our planet Earth is like a giant magnet as it contains huge amounts of magnetic metals in its core. Magnets all have a North and South pole like the Earth and we experimented to answer questions such as: Does a magnet have to touch an object to make it move? Are all magnets the same strength? Do magnets hold onto all metals?
We started the week by enjoying painting using magnets to move the paint around the paper. We placed a spherical magnet into paint on top of the paper and moved another magnet underneath which created the movement and patterns in our paint.
We ended the week by working in a recycling plant and making our own human recycling machines which used magnets to sort different materials ready to be recycled. We also learned about the life-cycle of a tin can and discussed some of the important issues of recycling in our world today.
In Maths this week, we used our knowledge of number bonds to help us with addition questions to multiples of 100. For example: If I know that 45 + 45 = 90, then I know that 450 + 450 = 900 because 450 is 10 times greater than 45.
We then used a mental strategy called ‘Round and adjust’ to help us with some tricky additions. For example: 364 + 9 =? We realised that if we rounded to 9 up to 10, we could easily add 10 to our number, then subtract 1 (adjust) to get the answer.
We practised this strategy with both adding 9 and 8 to a number. ‘When I add 8 to a number, I can add 10 (round) and then subtract 2 (adjust) because 8 is 2 less than 10’. Finally, we used this to help us solve problems such as 49 + 49 = ? So: 49 + 49 = 50 + 50 -2.
The focus of our Health and Wellbeing morning today was Anti-bullying week and friendships. To being the morning we discussed what Anti-bullying week is and what bullying means (Hurting someone on purpose over and over again). For our first activity we were split into groups and given a bullying scenario. We then had to role play the scenario and solution before performing it to the class. Our second activity was all about how to reduce bullying within our school. We watched the Anti-Bullying week video which discussed that change starts with us so we all make a pledge for how we will reduce bullying. To end the morning we made a class friendship quilt. We all painted our hands, printed them onto paper and wrote an acrostic poem about friendship.
This week in Topic, we have been writing our stories based on ‘The Egyptian Cinderella’. We used exciting adjectives in expanded noun phrases to describe and used commas in a list to make our writing even more exciting! We have also been learning about mummies and the process of mummification. We have used our new knowledge to help us make clay models of mummies which we wrapped in Modroc!
In Maths, we have been continuing our exploration of number by partitioning three-digit numbers systematically. We have been using our knowledge of number bonds to also help with addition of two digit numbers to find multiples of 10.
