Puzzles About 100

  • Fluently use operations within 100
  • Reason abstractly and spatially

The number 100 is a big deal. It pops up when we talk about place value and percent, and it's one of the most intimidating base ten blocks! These five puzzles about the number 100 will get your third grade kids' noggins spinning. Challenge your kids to practice not only their operations within 100 but also their abstract-thinking skills. These are all appropriate for the 3rd grade classroom with versions available for both the student and teacher.


Money Matters

  • Solve word problems involving money and fractions
  • Investigate details of U.S. and foreign coins

Take a peek at our Forgotten Stories of the Oregon Trail activity series, which are far more than just third grade math activities. They span all grades and touch on every subject while exploring 19th-century stories of women, Native American, and African American explorers and trailblazers. Students investigate what coins were like along the Oregon trail, including a strange-sounding six and one-fourth cent piece. There is a student version and teacher guide available.



In Our Corner of Space

  • Operations with numbers over 1 million
  • Model the solar system with mathematics

Make math fun by making it big. For third graders ready for a challenge, have them compare distances around the solar system. Students get an interstellar taste of how math is used in the real world. In this activity, which includes a student version and teacher guide, students also learn about the planets in our solar system by reading a passage and drawing them.


Find the Area!

  • Calculate the area of rectangles

Spin the spinners and make some rectangles! This math game has students playing a two-person game where both players use the spinners to generate the dimensions of rectangles, and whoever's rectangle has greater area wins the round. This game works well virtually by having the players roll a number cube they own or search for a virtual spinner. For more games and activities like this, check out HMH Into Math.


Coins in the U.S.

Auto Addition
