Team CH have continued their measuring work by exploring the word estimate. Using an unmarked straight line that was measured at 20cm the children investigated the length of the lines that were dotted around the classroom. All the children were aware of was the length of line, so they had to imagine a number line with zero at the start, ten in the middle and 20 at the end. Using this line, the children were able to estimate the length of the lines on the carpet by discussing number neighbours and other facts that they have learned.   

​ Teach CH have been strongly focusing on adding numbers that total more than 10. For example, 8 + 5. When we add two numbers which total more than 10 we use the “Make 10 and then” strategy. In order to use the Make ten strategy, we add or subtract the second number in two parts. The first part we add is always the amount we need to make ten. The second part we then add or subtract what’s left.   

This week Team CH have really enjoyed competing with each other in our high intensity fitness circuit.
