Bring Variety
Use paint chip samples, bright sticky notes, or picture cards to make tiling grids. Prepare a number of tiles ahead of time and try to use them all for a full grid. What happens if you have 7 or 11 tiles? What numbers can form a full grid?
Investigate how grids can be used to copy, enlarge, or shrink pictures. The deep math idea of distribution – along the whole grid, or just a row or a column – is very visual, accessible and thus exciting for kids. Change widths of rows and columns within the same grid to experiment with more complex transformations – and with very silly pictures!
Make a grid by folding large piece of paper in two, repeatedly! Investigate how small can you make the folded paper; what is the largest number of times you can fold, and how many cells will that make for the grid. How many cells are there after folding once, twice, three times?
