Summary of Unit of Work:
In order for students to progress in mathematics they need a strong foundation in Place Value. Using the inquiry process; tuning in, finding out, sorting out, going further, making connections and taking action, students expand their knowledge on decimals.
The unit begins with a tuning in, involving a pre-test with opportunities to learn through asking questions, videos, games, hands-on material, songs and explicit teacher instruction. At the end of the unit the students plan how to use their new knowledge on decimals and also complete a self-assessment rubric.
