Good luck today with the start of Book 4. Remember that we talked about the importance of estimating in metric and in standard measurement. Benchmarks are the key to estimation so help your kids find benchmarks that are familiar and useful. Our discussions in the first unit focus a lot on reasonableness and kids need a lot of practice with that idea. They want their estimates to be exact, so remember to discuss the idea of 'close to' and have the students decide if certain estimates are 'close to' the actual measurement. We are stepping back from being the arbiter of right and wrong and giving the students opportunities to decide and justify what is right.
It is a good idea to use the Missing Measures page from the student book because the questions on it are typical of logical thinking questions that you might see on a standardized test. I hope you have a good week with measurement and I will write about Unit 2 later on.
