This is a Common Core Aligned Smart Board lesson. This interactive product can be used as a mini-lesson or in a math center. The objective of this 50 page Smart Board product is to decompose and compose numbers from 10-100. In the first 25 slides, students are given a number and asked to drag the correct amount of tens and ones that make up that number. The next 25 units has the students counting the tens and ones given and composing the number on the Smart Board. These 50 slides have a seasonally appropriate Memorial Day theme. They also have answers that will appear on the Smart Board so they are able to work independently in a math center.
