We created beautiful stars and practised our ruler skills all at once! We can show you how to make one of these stunning stars - just ask us!
We had to carefully line our ruler up on two dots, hold it strongly with our other hand, and then push our pencil against the edge of the ruler and draw a line between the two dots. Using a ruler properly can be quite tricky. Some of us noticed pictures and shapes in our stars as we were creating them. Mariana noticed a kite as she was ruling, and Tiger noticed a bird's head with an open beak. We know that astronomers and star gazers also notice pictures and shapes in the night sky. These pictures and shapes can end up naming constellations. Can you think of any? After we'd ruled up our star shape, we used colours and patterns to decorate our stars. Mrs T then backed them onto cardboard and has put them on display in Room 12. You should pop in and see the finished stars!

This week some of our maths groups were looking at subtraction. There's never just one way to solve a problem, so it's super important to share our maths thinking and compare the strategies we've used. We can learn quite a bit off each other this way! We also like to show our workings, because sometimes if don't quite reach the right answer, we can go back and check. Sometimes when we're explaining to a buddy or our group what we've done, we notice a little error. Sometimes we're not on the right track at all! We don't mind that though, because we know we learn from mistakes! Nico, Noah, Kees, and Ben buddied up to share how they solved a subtraction number sentence.
We LOVE maths in Room 12 - and so does Mrs T's dog, Frank! Frank enjoys watching us working on using our place value knowledge to add two numbers together. We used maths equipment (Base 10 blocks) to help us build our understanding, and then talked with a buddy to compare our workings and share our maths thinking. Sometimes when we get different answers we need to work together to figure out how we can solve the problem. We know we need to justify our decisions and that it's ok to change our minds and change our answers. The most important part is the maths journey we go on!
Some of us have been working hard to learn the numbers that add to 10. We need to know them as quick as a flick. These include: 2+8, 4+6, 7+3, etc. If we know these basic facts, we can use them to add and subtract numbers easily, without counting. For example, if we know 4+6=10, we can use that basic fact to help us know 40+60=100 (4 tens + 6 tens = 10 tens). Today the Circles used their knowledge of numbers that add to 10, to quickly add together three numbers WITHOUT COUNTING. The idea was to find the compatible numbers - the two numbers that added together to make 10. Then the Circles needed to use their knowledge of teen numbers to add on the third number WITHOUT COUNTING, and find the answer. We found that we could add these 3 numbers really, really quickly! We had to work it out quickly because Mrs T "drove" the "train" of numbers into the "train station" where we couldn't see it. We practised explaining our maths workings to each other (you can see Irene doing this in the video below), and also writing down the number sentence that showed how we worked it out (you can see Niamh and Tavita's workings in the photos). |
