# CCSS.Math.Content.1.NBT.B.2: Limited (1)

Good review lesson for Gr. 1 to start the unit.

It is a great way to reach a variety of learners in kindergarten and first grade.

This is a good activity to teach the kindergarten CCSS K.NBT.1 - compose and decompose numbers from 11-19 into ten and some further ones. As written the lesson utilizes concrete objects, body movements, and pictorial representations to teach the concept of ten and some ones. As written the lesson may be a bit long for kindergarteners and it may not provide enough exploration with manipulatives to develop a strong understanding of the tens and some ones concept. The activities within the lesson are great for building understanding but it may be more effective if the lesson was spread out over 2 to 3 days. Prior to completing the clapping and tapping portion of the lesson (#2) it may be beneficial to give the students the opportunity to decompose teen numbers using manipulatives and use those groups to determine how many times they need to clap & tap or stand & sit. Also, when drawing the objects it is sometimes hard for students to draw multiple squares in a long connected line so to be more efficient and accurate to represented the group of ten with a long line and the ones could be represented by a smaller square. When the students work in their small groups to construct and deconstruct numbers it may be more beneficial to have the group of ten student stand like a stick/line and the ones students sit. At the end of the lesson to check for individual understanding students could be asked to represent a teen number as ten and some ones.
