Before Video
How can you count by 2s?ANSWEREach number is 2 more than the number before it. 2, 4, 6, 8, 10, 12.
I can, 3 + 3 = 6.
3 + 6 = 9. No, I can write 4 + 5 = 9 or 5 + 4 = 9, but the groups can't be the same size.
I can, 8 + 8 = 16.
9 + 9 = 18 and 10 + 10 = 20. I can't make 19. One way to make 19 is 10 + 9.
After Video
How can you tell if a group of objects has an even number of objects?ANSWERYou could pair them off. If there is an even number of objects, they will go into pairs with nothing left over.
You could pair them off. If there is an odd number of objects, there will be one object left over.
Even. I can make two equal groups.
Odd. When I put the objects into pairs, there is one left over.
9 + 9 = 18. 18 is even because it can be put into two equal groups.
