00:00 Great job! I was really impressed. Almost everybody was really taking those sentence frames and giving me such excellent thoughts.

00:08 I was very proud of you guys. Very nicely done.

00:12 What I want to ask you is, if anyone can tell me something they learned from doing this today? Something they learned from doing this today.

00:20 Give me a private thumbs up. I want everybody to come up with an answer. I won't ask all of you to share it, because we won't have time.

00:26 But I want everyone to come up with an answer in their head of something they learned. Something they learned.

00:33 Except you, Ryan. Since you only came in the last three seconds. I'll let you off the hook.

00:36 I learned math.

00:38 Can you be more specific? What did you learn about math?

00:41 I learned ... counting math.

00:46 Counting, so you learned counting. What type of counting did you learn or practice today?

00:51 Like.... 1 plus 1 equals

00:55 Hm. 1 plus 1. Did we use 1 plus 1's today?

00:58 No.

00:59 0 plus 10... equals...10.

01:06 I learned adding.

01:10 Adding, okay! So you learned adding. What can, how many numbers were you adding together?

01:14 Three

01:15 You were adding three numbers together? Like, 2 plus 2 plus 2? Or were you adding... two numbers together, or one number. How many numbers?

01:24 One.

01:25 That was a tricky question. So did you add one number together, like 4. You really-- did you-- Give me an example.

01:33 Let's do it that way. Give me an example.

01:35 7 plus 3.

01:39 7 plus 3. So you really had two numbers you added, right? Very good.

01:43 And what was the sum we were all trying to get to today? Everybody.

01:48 Ten!

01:49 Ten. I saw a lot of different ways to come up with 10. But Katherine, you didn't come up with the sum, tell us what you did, Katherine.

01:56 What I did is 20 take away 1 equals 19.

02:02 Okay. So we didn't have 20. But we did have, how many cubes did you have. Did you have 20 cubes all together? You did at the end, didn't you!

02:12 I forgot I gave you so many! So you used subtraction. Okay.

02:18 Great thoughts. I wish we could go on another minute, but that's recess. I'd like my line leaders and door monitor!

This lesson was difficult for some of the students, but was adaptable to meet the needs of the students who needed extra support as well as those who needed more of a challenge. I feel it is worth the extra planning time to have these differentiation options available. This really helps keep all students engaged.
