1. Unit B2 Day 3
This unit lasts for 3 weeks

2. Practice material including multiplying by doubling.
We will continue to explore patterns, properties and relationships.

3. 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

12. ? ? find patterns using 2s, 5s and 10s
What do we need to do for success? ?
Most of us should
All of us must
Some of us could
find patterns using 2s, 5s and 10s
find patterns using harder tables than 2s, 5s and 10s
find patterns, looking for them when negative numbers and decimals are used

13. Look at these number patterns.
Can you put the rule into words ?
105, 90, 75, 60
2.0, 1.5, 1.0, 0.5
4.7, 4.5, 4.3, 4.1, 3.9

14. 4 8 12 16
3.0
2.5
2.0 24 67
1.5 45 32
Work with your partner to create sequences for another pair to find.
They have to tell you the rule.

15. Has everyone found the number patterns in the grid?
Review
Has everyone found the number patterns in the grid?
Were all the patterns adding or subtracting ?
How about this sequence?
1.0, 0.1, 0.01, 0.001
Can you state the rule ?

16. Your turn-
Can you and your partner write a sequence based on multiplication or division?
2 minutes and then we will check to see if some of the rest of you can say the rule.

17. ? ? find patterns using 2s, 5s and 10s
How have we got on?
Most of us should
All of us must
Some of us could
find patterns using 2s, 5s and 10s
find patterns using harder tables than 2s, 5s and 10s
find patterns, looking for them when negative numbers and decimals are used

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

19. Tomorrow we will continue looking for patterns and saying whether a rule is true or false.

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