Make each number to ten with bingo chips, Chunk itz and blocks. Compare. All the expressions for each number are there.
Compare expressions as equal before addition facts.
The images above link to making sense of 5 + 3 = 6 + 2
We can translate the image to the blocks:
Can you still find 5 + 3 = 6 + 2?
When you use the ten frames as a referent is the focus on 8? Or is the focus on 10? Students need to relate 8 to 10 but do they have number sense for 8? Can they use the frame to RELATE the parts in 8?
Translate the concept to Chunk itZ. Now how do you see 8 and its parts? I started at 2 and made 8.
Use the diagrams to map your expressions.
Work with Inverses
If you think students have number to 7 you can start introducing inverses, but be careful. If you see finger counting, they are not ready. Flip cards get the thinking started.
I would “play with” flip cards as an oral task before I went to the What’s Covered Cards.
This powerpoint will help you introduce What’s Covered. WC Cards get Started 2019
I would not use this card unless students have automatic recognition of quantity. So I see 5 and 6 on outside which is 11 because I know 5+5 and I know 6+6 and it is one more or one less. So the card is asking me the difference between 11 and 19. I know it is 8 because 11 + 8 = 19 therefore I could write 19 – ? = 8 and then 19 – 11 = 8
Introducing Equal is a foundation that should come before equations.
SORTING TASKS focus on logic, not answers.
Sorting by 2 attributes is a foundation for all that is to come.
Sorting forms the basis for flexible thinking.
Attributes describe objects.
My year at a glance puts thinking skills first. Use them in a variety of contexts. Leave number to wait. IMAGE QUANTITY….
