Week beginning 18/05/2020 WALT: solve correspondence and logic puzzles
Hello Year 4! This week’s maths is slightly different. . . On the following slides, there a number of different puzzles for you to solve throughout the week. You need to work in a logical way, thinking carefully about the best way to solve each one. Some are best worked through using a system, others are more about trial and error. Different puzzles require different kinds of thinking. You don’t have to do them in order. You might choose to skip over a puzzle one day and come back to it later in the week. The answers for each puzzle are on the following slide. You may be able to come up with another correct answer that is not on the answer slide. It’s also important to keep up your times table practice, using maths shed, top marks or maths frame throughout the week. Enjoy!
