After some free play time, I decided to turn the blocks into a learning opportunity. Because each block is brightly colored, Sweetpea is fascinated with them. As she would choose a block from the bin, I would name the color. Sometimes she would hand the block to me and I would sort them according to colors.
The purple blocks quickly became her favorite to pull out and she would dig around in the bin to purposefully find a purple block. By the time we had to go pick up Buddy from school, she was recognizing purple, red, and yellow on a consistent basis.
Children learn best through play time and this was an easy way to add color recognition to our play with Mega bloks. I did not push her if she acted uninterested but kept a running commentary of what she was doing. This block playtime also became a lesson on "cleaning up" as Sweetpea helped to place the blocks back in the bin when we were finished.
