Multiplication

This week in math we learned about multiplication. One strategy we used is to make a map with horizontal and vertical lines. The lines make a grid with intersections.  If there are four vertical lines and five horizontal lines on the map, you can multiply horizontal by vertical to find the number of intersections. The number of intersections is the product. On the four x five map there would be 20 intersections.
