What Do You Notice? poster – Fractions on the Geoboard

Comments 0 Comment

Skills:
K-2: shapes, counting, area
3-5: congruency, area, fractions, equivalent fractions

This is similar to the Squares and More Squares poster. Like that one, this was designed around fractions but at a higher level. The dots for each square represent the dots on a regular geoboard. Each square is made up of 5 by 5 dots. If lines were drawn connecting each of the dots, the larger square would show 16 small squares (4 x 4 small squares). Each of these small squares represents one square unit.

Family Math Night Collaborative Project: Space Invaders

Family Math Night Collaborative Project: Space Invaders

Comments 0 Comment

I’m excited to share with you my latest Family Math Night Collaborative Project: Space Invaders. Here’s a photo of the final result. (There are actually 3 aliens to choose from in the lesson plan. This is alien #1).

Here’s some of the background information I include in the lesson plan:

In 1978, Tomohiro Nishikado, a Japanese video game developer, released his video game Space Invaders. It was such a popular game that it helped catapult video gaming into a global industry. The pixelated aliens in the game became a popular icon.

Pixels are small single-colored squares that make up images in computer graphics. These pixels are displayed as a bitmap, a rectangular matrix of dots. These pixels, sometimes called dots, are each assigned a specific color and are arranged along the horizontal axis (x-coordinate) and vertical axis (y-coordinate) of the matrix.
Computer graphics have come a long way in the last decade and look much more sophisticated today than they did back in 1978. But back when graphics were first being designed on computers, they had a “boxy” look. That’s because the screen displays (screen resolutions) were not as good as they are today.

Homework the FUN Way

Homework the FUN Way

Everyone loves to play games. They’re engaging, motivating, and fun. And from an educational perspective, they can be a powerful learning tool. Here’s what games can do:

  • reinforce skills learned in the classroom
  • develop mental math skills
  • encourage strategic thinking
  • foster mathematical communication
  • build confidence
  • engage parents

But one of the best things about games is that they offer meaningful practice in a way where kids actually want to do math. That’s because games, by their very nature, are fun. It’s not too hard to entice a child to play a game. And because of that, games offer important practice in a way that worksheets can’t.

Skills:
K-2: number recognition, pattern
3-5: pattern, addition

My youngest son visited the Basilica Sagrada Familia, a Roman Catholic Church in Barcelona, Spain and brought this pattern back for me as a gift. Here’s a photo of his gift: (And before you read the next paragraph where I describe the main pattern, you may want to discover your own patterns first.)

The Estimation Jars

The Estimation Jars

This year I decided to add the 0-120 number grids to my K-2 estimation jar. The number grids come from our Math Medley kits and kids can use dry eraser markers to “think” as they’re working out their estimation. Of course, there’s the thinking paper and the referents, as well.
