120s Gold Medals
Scaffolding the 120s Chart
Just like Making 10 Go Fish, we pulled out our Making 120 playing cards. It was the perfect chance to practice skip-counting by 10s to find pairs of 120. This simple game will stay in our math-center rotations on and off for the rest of the year.
Chart to Number Line – Say What?!?
Noticing Patterns on the 120s Chart
Another great game for recognizing number patterns on the 100s chart, as well as, ‘before’ and ‘after’ is SPLAT online! We played as a class on our SMART Board. Using different paint colors, students can visualize patters on the chart. We also played that students would take turns making number puzzles, “I’m think of a number that is one more than 15.” Everyone would circle it on their 100s chart (at their desk using a dry erase marker) and then, one special friend would SPLAT a number on the board.
After highlighting patterns on our 120s chart, we turned our charts into number lines! This was a Lightbulb Moment for so many of my friends. “The 120s Chart is actually just a number line?? Say what?!?!” If you try any activity in this post with your friends, this is the ONE! I blogged about it earlier in the month; you’ll definitely want to check it out here.
Real Life Splat
A partner-version of SPLAT, 4-in-a-Row offers students practice in saying and identifying numbers on the 120s chart. Students take turns pulling a number, saying it out loud, and finding the number on the 120s chart. Students ‘win’ the game by pulling 4 numbers in a row (horizontally, vertically, diagonally).
Using some partner games, we practiced adding and subtracting to 100. The best part? I was able to copy these games and send them home for families to play together. It was a perfect home-school connection.
We’re also loving our 120 Puzzles. I snagged a 120s chart from online, quickly cut each puzzle into 10-12 pieces, and placed each puzzle in a Ziploc bag. During our whole-group time, students worked with their table to make the puzzles (each player taking a turn placing a piece before the next partner could go), and during centers, students had the choice to work individually or with a partner. If you have multiple puzzles going, make sure to print each puzzle on a different piece of cardstock so you can easily sort the sets if they get mixed up!
Also, a highlight of our day is always Jack Martmann’s “Count to 100 Everyday” Song. It is a blast and gets my first-grade friends up and moving. Each decade is accompanied with a different exercise (windmills, running in place, shoulder shrugs). Since Jack’s song only goes to 100, we finish the last 20 numbers acapella. 😉
What are your favorite 120s activities? We’re always looking for ideas for our RtI groups, as well as, centers, so please do share!
