Unit B2 Day 5 This unit lasts for 3 weeks

Practice material including multiplying by doubling. We will continue reasoning and thinking about numbers and revise fractions.

I can investigate a general statement and say whether examples are true or false I can split a word problem into steps and work out what calculation to do for each step. I can explain what the answer to each step tells me I can present my solution to a problem, explaining the steps that I took in a sensible order I can add/subtract decimals in my head by using a related two-digit addition or subtraction I can find the double or half of a decimal by doubling or halving the related whole number I can use tables facts to multiply multiples of 10 and 100 and to find linked division facts I can check whether a calculation is correct and explain how I did this I can explain whether a shape has line symmetry and whether it has any parallel or perpendicular sides I can create a pattern that has two lines of symmetry or complete one that someone else has started I can say whether a triangle is equilateral, isosceles or scalene and explain how I know 5B2

Your task is to make up some clues for your partner to find your number. you need to be certain that there is only one answer. Some of you will work in pairs and some of you will work by yourself to start with.

Plenary Let's see if we can solve some of your puzzles? How did you make sure that there is only one answer? What words are you pleased that you managed to include?

You managed to do all your work? Wow. Well done.

Tomorrow we will look at nets of cubes and other 3-d shapes

Time to pack away please. But I want more maths!
