Learning Plan for Grade 4 - April 20-24th
Welcome to Week 4 of online learning. I’m so glad to see more students completing and submitting their tasks on Google Classroom. This is a great step forward!
This week, we are starting to integrate some scientific investigation of Light and Shadow. I hope you have fun exploring and learning some new scientific concepts.
As always, we are in this together and are here to support one another.
Math
Monday
I can use the array strategy to solve multiplication equations.
This is a quick review of arrays. Choose your own adventure! If you need review, choose #1. If your comfortable and confident with arrays already, choose #2.
Array: an arrangement of objects, pictures, or numbers in columns and rows. This strategy is useful when asked to find the solution to either a multiplication or division question.
#1 - Review: Arrays for 1 digit by 1 digit multiplication: Watch the video for a review and explore possibilities of using arrays with multiplication. https://www.khanacademy.org/math/arithmetic/arith-review-multiply-divide/arith-review-mult-intro/v/multiplication-intro
Task: Please take a moment and enjoy the learning game called ‘How Close to 100.” This activity will help you build more of an understanding of an array. You can print the handout directly from the website or you can make your own game board (you will then have the flexibility to make it as small or big as you please)
OR
#2 - Challenge: An array has 36 squares. How many rows and columns could there be? Find as many solutions as you can. Show your understanding through diagrams and/or words.
Tuesday
I can use the array strategy to solve multiplication equations.
Problem: Jenny planted a garden with 6 different types of vegetables. She uses one row for each different vegetable (i.e. carrots, beets, lettuce, cucumber, peas, and spinach). For each vegetable, she plants 80 seeds spread out across the row.
Draw a diagram of Jenny’s garden. How many plants in each row? How many in each column? Is it an efficient strategy to draw each individual seed? Is there a more efficient model you could draw? (hint: think place value)
- Write a multiplication sentence (equation) and solve it to show how many total vegetable seeds Jenny planted.
- Write a corresponding (matching) division sentence (equation). Explain your division sentence in your own words. For example, knowing the total number of vegetable seeds Jenny planted, what equation could show the calculation for how many rows? And another for how many columns?
Wednesday
I can use arrays to solve 1-digit x 2-digit multiplication questions.
Watch the attached video to see a great way to use an array for 1-digit by 2-digit multiplication problems. This is far more efficient than drawing out each individual square, isn’t it?
Arrays can be used to explore calculations such as 13 x 5 where the array can be split into useful chunks such as 10 and 3. This way, you can use known number facts to work out calculations for larger numbers.
For example: 13 x 5 = (10 x 5) + (3 x 5).
Part 1: For each of the following multiplication sentences (equations), draw the array and solve by using the distributive property (refer to the example). Choose 4 of these equations based on your comfort level with this concept (they increase with difficulty).
12x2=
3x14=
24x3=
16x2=
54x8=
5x47=
82x6=
4x77=
9x99=
Part 2: Can you write the corresponding division equations for 2 of the above multiplication equations?
Thursday
Here is another way to represent arrays as a further shortcut when working with larger numbers.
Video (start at 4:13): Matrix array strategy for larger numbers
Pretty cool, right?
Give it a try. Choose 4 of the following equations to test it out (they are the same as the equations used yesterday, so you can check your work!).
12x2=
3x14=
24x3=
16x2=
54x8=
5x47=
82x6=
4x77=
9x99=
Which array method do you prefer? Why?
Friday
I can use related multiplication skills when solving division equations.
After learning more about how to preserve the planet on Earth Day, Bob’s family decided to start using an outside compost bin. His family composted 49 kg of scraps in 7 weeks.
How many kilograms of scraps did they compost each week? Show your work using diagrams/manipulatives.
How many weeks would it take them to compost 42kg if they composted 6kg each week.
Do you notice a connection between the two questions above?
How can multiplication help you in finding the solution to a division question?
Literacy
In order to organize the tasks better, we have labeled them by the days of the week. It doesn't matter what order you complete them in. If you’d like to go out of order just “turn in” your work for the day you’ve completed.
Monday
Responding to a Picture
I can describe what I see
I can pay attention to details
I can share my understanding about a given image
Task 1:
Use the Image “The Jar Wizard” and the questions to practice different ways to understand an image by using the questions provided. (See attachment for image) Answer the questions in complete sentences or a paragraph.
- Who do you think this is?
- Why is he carrying all of those jars? What’s inside them? Why are they attached to his clothing? Couldn’t he just carry them in a bag?
- Why is he wearing this clothing?
- Is he going to open the blue jar? Why?
- Why is his other fist clenched?
- What does his body language tell you about his thoughts and feelings?
- Choose 3 words to describe this character. Justify your choices and explain why your words are better than anyone else’s!

Tuesday
Introduction to Light and Shadows
□ I can identify a wide range of sources of light, including the Sun, various forms of electric lights, and flames.)
□ I can organize my ideas and information using appropriate categories
Part 1: Find 5 or more different sources of light that have been created by humans and 2 sources of light that are natural.
Part 2:
- Make a visual journal page with the title “Light and Shadow”
- Draw a line down the middle of the page. Title 1 side “Sources of Light” and the other “What are they used for?”
- Draw a picture of the objects you find under “Sources of Light”. Make sure you label your picture.
- Beside each object, explain what these lights are used for under the column “What are they used for?” (for example:Source: microwave light. Uses: to see the food better to make sure it is cooked.)
Wednesday
Writing Prompt
Choose one to write about.
I can use details to tell the who, what, when, where in my writing
I can start with a catchy lead sentence to grab the reader’s attention
I can describe people, places and things using a variety of words and phrases in complete sentences
I can tell things in order (beginning, middle, end)
I can edit my work so it makes sense to the reader (read it out loud to yourself)
- Capital letters
- Ordinary words

- Spelling
Instructions:
Choose one of the prompts below, write for about 20 minutes (set a timer if you like). Read your writing to your parent/older sibling or out loud to yourself and make any edits needed before you turn in your work.
CHECK: Does it make sense???
Write about a time you felt really happy. What happened? What made you feel happy?
OR
