In this concept map activity, students will read, write, expand, decompose, draw, diagram, plot, round, and compare numbers. I created this for 4th grade, but it can easily be adapted for any grade. The 4th grade CCSS covered in this activity are:
4.NBT.A.2 Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
4.NBT.A.3 Use place value understanding to round multi-digit whole numbers to any place.
I've also included a blank concept map if you would like to write in your own categories.
