After looking at the samples, there was a clear need to have some time for learning dialog. We took a break and came back to the over arching idea of 100 patterns at a later time. Students viewed a quick Brain Pop Jr. video about patterns to 100 & then shared in think pair & share conversations about what patterns they personally observed on the 100 chart (rug).
This was followed up with an independent task and small group discussions that utilized Mathematical Practice # 3 Construct viable arguments and critique the reasoning of others. This was a great opportunity to solidify understanding and address misconceptions. Discussions included a large amount of peer feedback and accountable talk. There were quite a few Ah-ha moments as students built schema and participated in bridging dialog.
Instead of using the text book quick check, this mini lesson utilized a revised quick check/exit slip. Notice that the question is contrived to illicit a more explicit response from students. This was intentional to gain a more definitive overview of their conceptual understanding (2.NBT.A.2 & 2.NBT.A.1).
Quick Check Prompt: Madison counts 22, 24, 26. Zane says 28, 30, 32. Which three numbers come next in the pattern? How do you know?
