July 22

Today we started working on our multiplication unit.

I introduced a number of vocabulary words to students today and will continue to use them in class:

• factor(s) (the numbers you multiply together to get the product
• product (the answer for a multiplication equation)
• prime number (a number that is only divisible by 1 and itself: 2, 3, 5, 7, 11, 13...)
• composite number (a number that has multiple factor pairs: the number 12 is composite because it has the factors of 1, 2, 3, 4, 6, 12)
• multiple (any multiple of a number: the multiples of 3 are 3, 6, 9, 12, 15...)
• array (a grid style grouping of to show two factors multiplied to get a product)

We completed our own multiplication charts and students will get these back on Monday, freshly laminated so they last a good long while.

We also completed our 1-100 prime numbers chart where we discussed what makes a prime number and how we could see patterns within the 100 grid as we filled in composite numbers with colour.  

After that was complete, we talked about divisibility rules and how you could tell if a number is divisible by 2, 3, 5, 6, 9, and 10 (well...we'll get to 10 on Monday!).

And if all that learning wasn't enough, we also helped out our little buddy class with their second Freezie sale today, where profits will go to LAPS and BC Cancer Society.

Have a great weekend, and don't forget to practice, practice, practice!


Happy Friday,
