Are you quickly approaching your 100th day of school? This is a fun and exciting milestone in the school year, and for the first time as a homeschool mom I’m celebrating with my kids. I’ve been gathering tons of fun ideas to get out of our normal routine, while still learning important skills. I also created a STEM challenge especially for my kiddos who are in kindergarten, first grade and second grade because I wanted something they could all do together. This free download includes two 100th Day of School STEM challenges for grades K-6.

Looking for a fun and engagin STEM challenge for your 100th day of school? This post includes 2 different FREE 100th day of school STEM activities which can be used or adapted for grades K-6. Kids will love the challenge and exploring the math behind the design!

100th Day of School STEM Activities:

The free download at the end of this post actually includes 2 different STEM challenges for grades K-6. The first challenge is to design a structure out of 100 LEGO bricks. The printable is geared more towards K-3, though you could certainly do this with older students.

The second challenge is to create a design out of 100 pattern blocks. Again, the printable is geared towards grades 4-6 and focuses on fractions, decimals and percents, but you could definitely do this with younger kids and only use the first page of the printable.

Either way, these challenges will encourage creativity, develop problem solving skills, and engineering skills as kids have to use what they have to build a design that works.

I left the LEGO challenge open-ended, but you could be more specific with your students if you like. For example, build a _____ (house, tower, space ship, animal, etc.) out of 100 LEGO bricks.

Materials Needed for the 100th Day of School STEM Activities:

  • Assortment of LEGO bricks (100 per student)
  • Ruler
  • Small scale to weigh LEGOs (optional)
  • Crayons or markers
  • Assortment of pattern blocks (100 per student)
  • Student handout (get the download at the end of the post)

Getting Started with the 100th Day LEGO Challenge:

Obviously, you will need 100 LEGOs to complete this, as well as the printable handout.

I had my kids select 100 LEGOs before I told them anything about what we were doing. I didn’t want to influence their decisions. There were no specifications on sizes, types, colors, etc. of bricks. Only that they must use exactly 100.

I then had them put their choices into piles of ten to count by tens to 100 (to practice counting by ten and also make sure they had exactly 100).

If you are a classroom teacher, you may want to assign this for homework so parents can make sure they have exactly 100 bricks, and then they can bring their designs to school to complete and discuss the questions on the handout.

Once they each had 100 bricks, I told them to build something. It could be whatever they wanted, but it had to incorporate all 100 bricks. No more, no less.

They put quite a lot of time and effort into their creations, and it was SO fun to see them working and getting creative.

They didn’t just stick the bricks together, they thought it through and designed unique pieces that they then played with the rest of the day.

One of the creations was a “crazy mobile” which included a slide, a working see-saw and a snack station.

Another creation was a spaceship with a dinosaur on it. It had blasters and shields and a fish tank for their food.

After building and designing, it was time to analyze their creations. The 1ooth day STEM printable includes questions to dig deeper and explore the math behind their creation.

It includes questions such as “count it,” “measure it,” “graph it,” etc.

Please note, the “measure it” section includes a place to weigh the design in ounces. If you would like to weigh them and compare designs that used lots of large pieces to those with lots of small pieces, you will need a small kitchen scale.

This is optional, though. You could still complete the challenge and just measure length and height. 🙂

100th Day of School Pattern Block Challenge:

This free download also includes 2 pages to complete a STEM challenge with pattern blocks.

This would definitely be a fun activity for younger kids, and you could still use the first page of the download, which ask them to “sketch it,” and “count it.”

A second page is included, however, which allows older kids to explore their designs a little more in depth.

Because there are exactly 100 blocks, I thought this would be a great opportunity to review or introduce the relationship between fractions, decimals and percents.

So after counting the total of each block type, students will write each number as a fraction, decimal and percent of the whole.

You could then discuss as a class how to determine these numbers, how to write them in simplest form, etc.

There are then a few more discussion questions, such as “Is your design symmetrical?” and “Which block did you use the most? The least? What’s the difference between the two?”

Hopefully, through this fun activity, you will have the opportunity to review and explore a variety of math concepts.
