Get a small decal from the teacher after successfully breaking through the customs. Start the challenge!

Teaching reflection

In this activity, the children are enthusiastic and interested. They can boldly try all kinds of operation materials and record the results in their own way. I provide children with a big operating platform and thinking space, so that they can find and solve problems through comparison and discussion in operation.
