Math Project-Based Learning: Place Value, Rounding, Comparing | 4th Grade Math

This 5-day project-based math resource applies math concepts in a real-world scenario to teach students about place value. In this 5-day unit, students will use place value concepts such as rounding and comparing numbers to plan a road trip. This math project is engaging and authentic. Plus, it’s available as both a digital and print resource.

This project-based math resource covers concepts of rounding and place value, and is aligned with the following 4th Grade Math Common Core State Standards:

CCSS.MATH.CONTENT.4.NBT.A.1
Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 √∑ 70 = 10 by applying concepts of place value and division.

CCSS.MATH.CONTENT.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.

CCSS.MATH.CONTENT.4.NBT.A.3
Use place value understanding to round multi-digit whole numbers to any place.

This resource is available in both Printable & Digital Google Slides versions.

What’s included in this resource:

• Background Knowledge: Using a KWL, students will build background knowledge around planning a road trip.
