If you’ve ever followed a recipe to bake cookies or make your favorite meal, you already know one of the secrets to mastering the division algorithm:it’s all about following steps in the right order! There are measurements, steps, and rules to remember. But once you get the hang of it, it becomes second nature.
A recipe tells you what to do, one step at a time — and long division works the same way!
The “recipe” for long division goes like this:
Divide
Multiply
Subtract
Bring down
(Then, repeat!)
If you follow these steps carefully and in order, your math will come out just right, like a batch of perfectly baked cookies !🍪😋
Use this video to help you practice the steps. Pause the video and write down the problem. Solve it on your own and then press play to watch the steps. If you go a different quotient, find your error and fix it. Then, try the next one! Keep going until you get the hang of it.
Oh, and don't forget to send all remainders to me!
There are many ways to solve multi-digit multiplication problems. Choose the strategy that works with your brain! Here are three of them...

No matter which strategy we use, the solution remains the same!
427 x 24 = 10,248
If you do not have your X Facts memorized, 5th grade math can take a long time to calculate. I would suggest gluing a Multiplication Chart onto the inside of your Math notebook cover. That way you can refer to it all year.
Using exponents is an efficient way to write numbers that have a few too many zeeeeeros.
The exponent (or power) tells us how many zeros are in the number when the base number is 10.
The image below has a place for everything with everything in its place. The base can be any whole number, but today we are only focusing on the POWERS of TEN!
Here are the vocabulary words for this lesson:
powers of ten
base number

This month we are going to design catapults that will FLING autumn-ish projectiles 6 feet or more!
Catapults use weights and levers to send large rocks or
other things into the air. They were commonly used as weapons during the Middle
Ages. Catapults do not throw as far as modern weapons do and are not useful in
modern warfare.
During the Medieval Period, catapults were used as weapons
to throw rocks or other things such as hot tar, that would cause damage to
something else. Often, catapults were set on higher ground or on castle towers
to let them shoot farther. They shot rocks to break castle walls or hot tar to
set the target on fire.
Let's design mini-catapults!
Use items from around your house to design a free-standing mini catapult that will launch October themed projectilesfarther than 6 feet! Projectiles can be anything related to fall - apples, mini pumpkins, acorns, fall-colored pompoms, Halloweeny stuff, etc.
Send Mrs. Sol pictures or movies of your experiment to share in class.
