Building sentences is a hard topic for my firsties. It takes us a lot of practice to create sentences that have the correct word order and details. So we start early in the year by working on unscrambling sentences to get us thinking.
For language we have been learning how to make arrange words in a sentence so that they make a complete thought. The kiddos each received a pan, an egg, and small strips of yellow paper. I told the kiddos to glue the strips on the pan in any order they wanted to. The kiddos then unscramble the words and wrote the sentence.
