Video games console sales (updated 2022) - The video game world is constantly changing and improving.

This is sure to be a hit with kids as they work on their data analysis and number sense through the context of video games.

On November 20, 2022, the World Cup of soccer will begin in Qatar. This is a world-wide competition and up until the finals, teams have only been able to play each other in a selection of countries that are relatively near.
We have two different activities involving the logic of setting up a fair draw and the number of matches that each team may have to play.
The harvest must be nearing completion now and growers are selling their product to make cranberry juice, jelly, sauce, and of course, fresh berries in time for Thanksgiving.
In this activity, students learn about how they are grown and harvested; estimate their size and quantities; and see what they can deduce from published statistics.
On the morning of November 8, 2022, many of us will be able to see the last full lunar eclipse until March 2025.
Luckily, many of us will be able to see the eclipse pretty close to when we would ordinarily awake.
In this activity students will come to an understanding of the alignment of the Sun, Moon, and Earth during a total lunar eclipse. They are asked to deduce from a graphic who will be able to observe the event and who on Earth will have no opportunity. They research and report to the class why the Moon will look reddish during the eclipse.
