Today we started one of my favorite topics – the standard algorithm for division. We will revisit this topic multiple times this year, as it is a really important skill. We started by examining how this ancient algorithm works and how we use it. We saw how fast and accurate it can be!

For warm up today, we completed an error analysis of rounded decimals. Our lesson was a brief review of adding decimals.

Hi 5th graders, today we had a whiteboard lesson practicing the standard algorithm for multiplication. So, no lesson notes today. Instead, we have announcements and new job rotations. See you tomorrow!

Hello Families, On Friday I sent home the results from the Renaissance 360 Universal Screener for Math. The Renaissance Screener helps to gauge progress against grade-level skills (though not student math ability). We use the results to see where students need extra support or additional challenge. More info about the test is below or at the RenaissanceContinue reading “How to read the Renaissance 360 Universal Screener”

Today’s lesson starts us on Unit 4. We are learning Skill 9: I can multiply using the standard algorithm. We learned how this algorithm works and it’s benefits in speed and accuracy.

Here’s a summary of what we covered in Unit 3, prime and composite. This is the first unit of entirely new material for 5th grade. Yay! Skills: Skill 6: I can identify factors and multiples. Skill 7: I can identify prime and composite numbers up to 100. Skill 8: I can use divisibility rules. LessonsContinue reading “Unit 3 Overview: Prime and Composite”

To wrap up unit 3 on prime and composite, we learned some of the divisibility rules which can help us know whether a number is divisible by another number. Today we did the rules for 2 and 3. We will come back to these tomorrow and in the week ahead. It’s best to practice theseContinue reading “Skill 8: using divisibility rules”

This lesson focused on how we can use general rules or patterns to help identify prime and composite numbers. We also started building a visual summary of the primes to 100. We will come back to that summary every couple of days.

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