Good afternoon! Our objectives this week: – Complete Snapshot 1 on Friday: Snapshot 1 is an assessment taken by all district students to assess our learning and skills over the first seven units of class. The test is 18 multiple choice questions. It is an important opportunity to show what you’ve learned! – Complete SnapshotContinue reading “Weekly objectives (Oct. 25 / week 10)”

Teach Your Family Friday: How to find prime and composite numbers up to 100
This weekend, share your learning with a family member or friend. The video above shows how to find all the prime numbers up to 100 in a very easy (and ancient algorithm). This is the same method in your notebook. Have a great weekend!
How to read word problems (and find the operations)
Today we spent time learning how to read a math problem – particularly a word problem. We saw how often the challenge is understanding or “disentangling” what the question means before we can solve. Being methodical and using these strategies will help. Our notes and practice today shows the steps to use when reading aContinue reading “How to read word problems (and find the operations)”
How to use this blog
Hello! I’ve put together this blog as a resource for you. Each day after school I will post a picture of that day’s lesson notes. You can use the daily post to check your notes, finish copying down work we did in class, or find what we did if you were absent. I plan alsoContinue reading “How to use this blog”
Mini lesson on drawing fractions
In preparation for our fraction test today, we spent a few minutes reviewing how fractions can be represent using arrays or diagrams. The picture above shows a common (and tricky!) way.
The order of operations
Today we took a more detailed look at the order of operations. We noticed how it is important to work through each level or layer of the operations (like a checklist). We looked at different kinds of grouping, why we use grouping symbols, and how we need to be careful to solve the operations fromContinue reading “The order of operations”
The gold trading story … also known as the order of operations
Our new unit today (Unit 7) began with a short story to show how two islands trading gold bars made a mistake because one always multiplied first and the other always added first. We saw how, applied to the real world, we need to have an order in which we do our mathematical operations. WeContinue reading “The gold trading story … also known as the order of operations”
How to use the standard algorithm for division with a two digit divisor and a four digit dividend
Our lesson today increased the complexity of the example we are using to learn the standard algorithm. We learned how the same steps apply to dividing a four-digit dividend by a two-digit divisor.
How to use the standard algorithm for division
Today’s lesson focused on the steps we use for the standard algorithm. We compared today’s example to the simpler version from yesterday without a remainder. We noticed how the algorithm works because it takes advantage of place value to solve the question without many steps.
Division review
The second part of Unit 6 is understanding how to use the standard algorithm for division in word problems. We begin by reviewing our division vocabulary and connecting estimation and the partial algorithm (“magic 7”) to the standard algorithm.
