The 100th Day of School. A day for celebrating, reflecting, and ideally – a little bit of learning! Between a recent Winter Break, the 100th Day of School, and Valentine’s Day, as a teacher I longed for normalcy. Just a few stretches of our traditional, daily schedule and routine with some 100-pizazz thrown in. The math centers and technology tools showcased in this post are just that.
Race to 100…Bumped Up!
In the traditional Race to 100/120 math game, students take turns rolling dice and moving their counter on the playing board. Ideally students are counting aloud as they pass each number…but really they are counting the number of spaces they are supposed to move. In this bumped-up version, students work to fill in the missing numbers on the chart as they move, as well as, write the coordinating equation.
Go Fish…100 Style!
Our traditional Making 10 Go Fish has been upgraded to 100. Using ten-frames as a visual support, students work to find combinations of 100 (or 120). Make these simple and inexpensive pool-noodle cardholders to make students easily hold the playing cards.
Splat 100 – Online 100s Chart
The 100th Day of School is the perfect time to revisit Splat. This online-based, free, sound-making chart is PERFECT for your special celebration. How might you use it?
- Mystery Number – Have students create mystery number riddles individually or in partners. Students can use their knowledge about numbers to create riddles – place value, addition and subtraction, odd and even. Use the large display of the SPLAT board to solve the riddles as a class. It’s the perfect way to review LOTS of the skills you’ve learned in the previous 99 days.
- Noticing Patterns – With 7 different transparent number-highlighting colors, SPLAT is the perfect time to notice patterns. Looking at columns and rows, what happens when we move along the diagonal, what do the matching equations (addition and subtract) look like. So much exploration and connection-making can happen. You might even turn the 100s chart into a number line. Who knows?!
- Arrow Patterns – Arrow Patterns are math riddles in their finest form. A little abstract and different, these patterns add challenge to your 100s chart as students practice adding and subtract 1 and 10 to find a mystery number. You can snag some different prompts here or have students make their own!
Skipping Counting by 10s
Close the Circle is a fun way to practice counting to 100 by 10s. Each linking cube represents 10 with students attempting to build towers of 100. When a circle has a tower of 100 it is closed. The students with the most closed circles at the end of the game wins. This is a low-prep game that only requires a dice, linking cubes, and the playing board. Plus, it’s a great way to concretely build an understanding of overflow or regrouping. When students “close” a circle and still have linking cubes left, they add them to a different circle!
It’s important for students to be flexible in their math thinking. Recognizing that numbers can be composed and decomposed in different ways builds number sense. In this sort, students are given many different representations of 100 (tally marks, ten frames, place value, addition, subtraction) and are asked to integration their comparison skills. Is it 100 or is it greater/less than? With 2 different header options and then, 3 levels of playing cards – all students will have the just-right challenge.
100th Day eBooks
Epic Books for Kids has a great collection of 100th Day books. From looking at life 100 years ago to different ways to make 100 to what 100 pounds looks like, there are SO many awesome math connections. It’s a perfect way to integrate tech into your day, as well as, a bit of normalcy. Depending on your grade-level, you might have students work in pairs to read the books together. (Read more about EPIC here.)
So friends, here’s to a day of celebrating, reflecting, and small pockets of normalcy! The centers and resources shown in this post are ideal for the 100th Day of School celebrations OR any time of the year that your students are ready. Additionally, all 7 games are provided in 100 and 120 versions to match your celebration and/or state standards.
