You can see 8 = 5 + 3 in the blocks. Thinking 101 2014 glorway@telusplanet.net
Unsnap to show. Record the equation. 8 = 5 + 3. Thinking 101 2014 glorway@telusplanet.net
Unsnap to demonstrate 8 = 4 + 4. Record the equation 8 = 5 + 3 8 = 4 + 4 Thinking 101 2014 glorway@telusplanet.net
Snap the 8 back together. Can you see 8 = 6 + 2? Thinking 101 2014 glorway@telusplanet.net
Unsnap to demonstrate 8 = 6 + 2 or 8 = 2 + 6 8 = 5 + 3 8 = 3 + 5 8 = 4 + 4 8 = 6 + 2 8 = 2 + 6 Thinking 101 2014 glorway@telusplanet.net
Snap the 8 back together. What if you just unsnap one block? Thinking 101 2014 glorway@telusplanet.net
Do you see 8 = 1 + 7 or 8 = 7 + 1? Thinking 101 2014 glorway@telusplanet.net
Record the equations. 8 = 5 + 3 8 = 3 + 5 8 = 4 + 4 8 = 6 + 2 8 = 2 + 6 8 = 1 + 7 8 = 7 + 1 Thinking 101 2014 glorway@telusplanet.net
I used the Chunkz 5 + 3 = 8. Build this 8. Record the equation. Thinking 101 2014 glorway@telusplanet.net
Now as I look I see 4 + 4 is also in 8. Thinking 101 2014 glorway@telusplanet.net
Record 4 + 4 = 8. Thinking 101 2014 glorway@telusplanet.net
If 5 + 3 = 8 and 4 + 4 = 8 then I can also write 5 + 3 = 4 + 4 Thinking 101 2014 glorway@telusplanet.net
Heres a different way to build 8 with 5 and 3. Thinking 101 2014 glorway@telusplanet.net
Do you see 8 = 5 + 3? Thinking 101 2014 glorway@telusplanet.net
But now I also see 6 and 2 is in this 8. Do you see where? Thinking 101 2014 glorway@telusplanet.net
Heres my 6 and 2. Can you see it? 6 2 Thinking 101 2014 glorway@telusplanet.net
I could describe this 8 as 5 + 3 or 6 + 2 Can you see both? Thinking 101 2014 glorway@telusplanet.net
If 8 = 5 + 3 8 = 6 + 2 then 5 + 3 = 6 + 2 is true. Thinking 101 2014 glorway@telusplanet.net
You build another 8 with ChunkitZ. Then look for and record the facts you see inside. Thinking 101 2014 glorway@telusplanet.net
I made this 8 with 3 + 2 + 3 But now I see 4 + 4 in it. therefore (3 + 2) + 3 = 4 + 4 I know that 3 + 2 = 5 so I could write 5 + 3 = 4 + 4 Thinking 101 2014 glorway@telusplanet.net
What expressions make 8 in this puzzle? Thinking 101 2014 glorway@telusplanet.net
8 = 2 + 2 + 2 + 2 8 = 6 + 2 8 = 5 + 3 8 = 4 + 4 Can you explain why 6 + 2 = 7 + 1 is true? Thinking 101 2014 glorway@telusplanet.net
