We've been working hard thinking about and problem solving on open number lines during our math lessons. Once two numbers are designated on the line, every other number has a proper place it belongs. We have to compare numbers, work within different ranges, think about tens and ones, and use flexible thinking to figure out what numbers go where on the open number line. It's hard work! We've also been doing some adding and subtracting on a floor number line by having a frog "hop" on it forward or backward by 1s or 10s.
Then we've had time for workplaces several days this week during the last portion of math time. Here we are busy at some of the games. This is called Tower Race:
Cats & Mice (adding, comparing, subtracting, using greater than and less than symbols):
Doubles Plus or Minus One:
The Frog Jump Game:
