During Reading, I like the to be engaged in independent work so I can work, uninterrupted, with small reading groups. This year, I've been trying the management system described in The Daily 5. As a part of their weekly assignments, the children complete various Word Work (Spelling) activites. I love the Word Ladder Kit from Primary Concepts. Children have their own sets of letter tiles and can work at their own pace.
Below is one an example of Word Ladder. The children build each new word by changing one or two letters or rearranging the letters.
