Today’s lesson returned us to prime and composite. We examined how arrays can show whether a number is prime or composite.

Please find below a short guide to reading your (or your student’s) math grades.  Grading approach: Grades are a useful way to measure progress to mastery of the various skills we are learning, but they don’t always reflect a student’s true ability. As I tell our students “your ability grows with your effort”, so IContinue reading “How to check your math grades”

5th graders, I noticed that some of our sled-paced lessons on Zearn are touching concepts I haven’t taught yet. So, today we are taking a moment from prime and composite to learn about exponents and powers of ten. This will help to keep you moving through Zearn and also help with multiplication and division soon.

In today’s lesson, we reviewed a selection of questions from our Unit 1 test. These three questions are the ones with the lowest average score among all students.

Today we took a deeper look at factors and multiples. We studied different ways to find factors and compared the to multiples. After our lesson on factors and multiples, we connected multiples to prime and composite by finding the multiples of each prime number up to 13. We saw how this algorithm lets us filterContinue reading “Skills 6 and 7: understanding factors and multiples, prime and composite”

Our lesson introduced two new skills: identifying prime and composite numbers and understanding factors and multiples. We learned the early prime numbers (2,3,7,11,13) and how they are related to multiples and factors.

Today we looked at different ways to estimate, including rounding and compatible numbers.

Here’s a summary of the work we’ve done for Unit 2. (This unit is a review of fourth grade material, with the addition of using the thousandths place value and learning more estimation strategies). Skills: Lessons and mini-lessons: Extra practice: Download extra practice questions
