Doing words I

Doing words - I Doing words help you say what people and animals are doing. We simply add "ing" to the doing word (e.g., climb) in some sentences. Example:  The snail is climbing up the wall. We repeat the last letter when we add "ing" to some doing words (e.g., slip). Example:  The snail is slipping down the wall. Type "ing" in the correct form to each doing word in the brackets. Then type the word to fill each blank below.
