These are part of our Math Fluency Boxes, which are full of activities to help us become fluent with numbers. We have filled our boxes with many activities, and we found a new favorite today: Hundred Grids. We added an activity that has a blank hundred grid on one side and a regular hundred grid on the other.
There are so many possibilities with hundred grids.
We can fill in numbers in counting order, shake dice and make our best guess to fill in specific numbers, or fill it in randomly...
....but our new favorite game is "Guess My Number."
For the game Guess My Number, one partner has a number in mind and the other asks questions to narrow down possibilities to try and find out the partner's number.
We found out that some questions are somewhat helpful and cancel out one or two numbers (like, "Is your number 68?") or some questions can be very powerful and can cancel out lots of numbers (like, "Is your number less than 50?").
We are getting smarter as mathematicians every day!
