Now that we’ve explored the 4 basic shapes, it’s time for some inside-outside exploration. As you work a round (pardon the pun) the house or childcare center today, help kids notice the shapes. Set the timer for 1 minute and send the kids off to find and count the most squares, the most rectangles, the most circles and the most triangles. This can be played with just 1 child, too, and 1 grownup but be prepared. Some kids are very visual and may find more than 
the adult! Since eyes are circles, they can play I Spy and look for a shape.
For outside, take a walk around the area and notice shapes. Picking out shapes that they see around them helps children develop visual kindergarten readiness skills such as observing and visual discrimination. It’s really quite a complicated skill because kids need to have a mental picture of shapes and then compare what they see to those mental images, sorting thru them to find a match. What shape do you see most often?
