Even young preschool students and toddlers can problem solve. Students learn at very young ages how to do things and figure out things on their own. They think about it. They work at it. They get frustrated. They succeed.
This young 2 year old student worked for awhile with these big waffle blocks and a crate. She saw that these blocks might just fit inside the crate. She placed one block in the crate. Then she tried putting another block in the crate. She saw that it was not going to work just as she had planned so she removed the blocks and tried it a different way.
Then she laid the blocks out on the ground as a sidewalk pattern to enjoy walking on them.
