The final week of our Year 3 Maths Programme! This week we start by checking some of the skills that children should have acquired during this year. They include: Rounding to the nearest hundred; remembering that if the number ends in 50 to round up to the next whole hundered. Partitioning three digit numbers in various ways. Subtracting 2-digit numbers mentally; many adults have problems with these, but there are various strategies that can be used, including counting on, or starting by subtracting the tens, or adjusting (e.g. subtracting 30 and adding 1 to subtract 29). Adding amounts of money mentally and writing the answers as pounds. We finish the week, and the year, with a fun addition investigation. This investigation  is a development of the caterpillar investigation and hexagon challenge, but using multiples of 10. The shortest and longest routes can be found, but children also need to be confident enough to add several multiples of 10 together, making it suitable for around Year 3 on. The initial task of finding a route through which is less than 200 would be a good way of introducing the investigation to the whole class, perhaps using a whiteboard.
