At Home Formative Assessment
BlubbrQuiz
Students will complete this online quiz as part of the at home assignment and bring a print out of their scores. I will be able to tell whether or not they've watched all 5 videos that were part of the homework assignment and if they are understanding concepts that go along with them. A part of each video is shown along with a question for each that the students have to answer. Then, they are given a score based on how well they do.

Enrichment Activities:
- Watch the following sketchcast video at your seat on your individual computer (with earphones) and follow instructions for use with dry erase board. Raise your hand if you need teacher assistance while completing the individual practice portion. We will check together as a group in a few minutes.
Partial Product Review Sketchcast
- After you are assigned a partner, use the dry erase boards to create 2 digit by 2 digit multiplication problems for your partner to solve. The partner solving the problem will walk the other person through each step. The person creating the problem will have a calculator to double check that the partner got the right answer. This will provide extra practice and an opportunity to check for understanding.
