The activities included in this Unit are aligned to first grade common core standards. There are activities included where students represent numbers in a variety of ways- including pictures, base ten, words, and tallies. There are also Depth of Knowledge questions included that require in depth understanding of tens and ones to locate numbers on the one hundred twenty chart. They must also complete one and two more than a given number with representations. I created this unit to provide students with a deeper understanding of numbers and place value. I hope you find it helpful when teaching your first graders number sense and place value!
