• ### Activity 2 / Rounding to the Constitution Worksheet

Before beginning this easy and traceable worksheet, ask your students who James Madison is. If they know, good job to you as their teacher. If they don’t, you can take the time and opportunity to give them a quick history lesson. Now, ask them to round the numbers in the tracing sheet down to the nearest numbers. Your students must draw a line through the numbers that round down to 400 or 500 to help James Madison reach the Constitution.

• ### Activity 3 / Rounding on the National Mall Worksheet

Math can be found across the curriculum, even in social studies! This brilliant worksheet brings together these two unlikely subjects by tasking learners with rounding numbers to help record how many visitors visited various monuments and memorials in Washington D.C. To complete, remind children to round down to the nearest hundred as they read the attendance numbers in red next to each picture. To extend the lesson, talk about each monument to teach or refresh your child’s knowledge of these important national landmarks!

• ### Activity 4 / Rounding Natural Resources Worksheet

Math concepts have real-world applications that can be applied throughout the curriculum! Use this incredible worksheet from Kids Academy to review rounding skills, as well as natural resources. While working, this page tasks learners with viewing pictures and the amount of natural resources, like gold, iron, copper, and silver. For each, help your child round down to the nearest hundred. Feel free to also use this page as a way to jumpstart a science discussion about natural resources found on the planet!
