Homework: Prepare for Division Quiz

Hi Students,

This is a friendly remind that you have a Division Quiz on: Thursday, June 11. 

On the quiz, you may be asked to: 

• Represent a division equation using a picture

• Write a division equation to match a given picture

• Solve division equations up to 3-digit by 1-digit using strategies, such as "Drawing Groups", "Long Algorithm", or "Short Algorithm" 

• Solve a division word problem in pictures, numbers, and words (a sentence answer)

• Create a division word problem

• Solve questions that include remainders

The "Drawing Groups" strategy

Since this strategy is unfamiliar to many parents, I am going to describe it here using the language we used in class: 

1. Think about the problem. An example of what 48 / 4 means is that you have 48 of something, and you are sharing that out equally between 4 people.

2. Draw circles or stick people to represent the number of the divisor (4).

3. Use a number you can skip count by easily (like, 100, 10, 5, 2...). Share out the same amount to each person/group. For example, in the picture below, the student started by giving each person 3. 

4. Calculate how many you just gave out in total (3 + 3 + 3 + 3 = 12).

5. Subtract 12 from your dividend to see how much you have left to give (48-12 = 36).

6. Do steps 3 & 4 again until you have shared out all that you have. 

Count up how many you have in one of the groups. This is your quotient (answer). If you have any leftover, write that as your remainder (R = ___).

Zoo Designs

In Math with Ms Elder, we are using our Multiplication skills to calculate the area of rectangles. We are using our creativity and art skills to design zoo enclosures. For the Math, we calculate the dimensions and area of each enclosure. Here are some photos of us working: 

Adding and Subtracting Quiz

 

 Adding and Subtracting Quiz

April 1 (Wednesday)

We have been working hard on our adding and subtracting skills. After the break, we will put those skills to the test on a quiz. The quiz will include calculations of 4 digit numbers in both operations and problem solving.

Should you wish to practice any of these skills, questions and exemplars can be found on google classroom.

Multiplication Work

A Class Favourite: Multiplication Luck!
Rules are posted on the Google Classroom

Over the past five weeks, we have been learning what Multiplication is, how to represent it, and how to solve problems related to it. While doing so, students have explored patterns in the Multiplication table and gained fluency when solving equations up to 12 x 12. We will now be moving on to Area, which reinforces an understanding of Multiplication arrays, and then larger Multiplication equations, up to 3-digit by 1-digit numbers.  

It is essential that students know their times tables up to 12 x 12. As we build on this foundation, the problems will increase in difficulty. If they cannot skip count yet, they need to practice at home. 

On Google Classroom, there are a plethora of resources for helping students. Some kids learn best by singing their times tables, some enjoy card or dice games. There is an interactive Multiplication Grid where students can highlight multiples of each number and colour-code them. In class this week, we started creating one more tool for helping: a "Multiplication House." 

Students chose the times table they most need to practice. They created their own design that has flaps, such as a school bus with windows that open, a pizza with pepperoni flaps, or a cell phone with swinging keys. On top of each flap, they wrote the factor they are multiplying by. Under each flap, they wrote the answer (the "product"). This is a tool students can use independently for practice. Stay tuned for more pictures next week of our finished product! 

Parents, thanks for your help in ensuring your child knows their times tables up to 12 x 12! :)

• Draw arrays to match a given total (ex: draw as many arrays as possible with a total of ___)
• Explain how you know there aren't more possible arrays using clear Math language
• Solve Multiplication equations up to 12 x 12
• Explain strategies for each times table up to 12, using clear Math language (ex: There is a pattern in the ones place. Each digit in the ones place increases by one.)
• Solve word problems relating to Multiplication by showing the answer as a picture, an equation, and a sentence answer
• Create word problems that use Multiplication.

If you have any questions, reach out to Ms Elder.

Intro to Multiplication

This week with Ms Elder, we started learning about Multiplication in Math. 

Multiplication means repeated addition. It is making groups and counting up the total. The two numbers you are multiplying are called the factors and the answer to a Multiplication equation is called the product. We can represent Multiplication by drawing pictures of groups or arrays. 

This week, Ms Elder put us into groups and assigned each group a times table. With our group members, we are responsible for making a poster that shows the strategies you can use to multiply by that number. We will also put patterns we see and a hundreds chart with the multiples highlighted. Here is an example we made together, with some tips to make a great poster: 

Here are some photographs of us hard at work:

By the end of Grade Four, we need to have memorized our multiplication facts up to 12 x 12. There are games and songs and ways to practice posted on the Google classroom.

Mandala Writing

After drawing personal symbols to share who we are and what we like in our manadala art with Ms. Elder (not to mention learning about radial symmetry!), we then learned how to write a paragraph with Mrs. Jamroziak.

We did a rough draft on paper, typed them up, received feedback and worked to improve our topic sentence, supporting details and sentence structure!

Here are some of our stellar topic sentences!

When you think about a mandala, do you think about learning other people's ways of thinking? - Effie

My mandala is like a puzzle. Every piece you place you learn more about me. - Jackson

My mandala is like a tree and every leaf that falls teaches you about me! -Oliver

This mandala shows how unique I am. It's like everything hidden is revealed head to toe. A photo of me is made in your mind. - Cora

This mandala will be like a compass. It will guide you through my identity. - Oscar

This mandala is like a map leading you to a treasure but instead of money or gold it is the knowledge of who I am. - GH

1. What did you enjoy about writing your mandala paragraph?

• I liked sharing what I love. - Jackson
• I liked that it was a big project so we had a lot of drafts. - Wynn
• I enjoyed sharing my likes and it was the first time in a long time that I thought about what I liked. - GH
• I liked that we could write about the things we like and other stuff. - Oscar

2. Why do you feel proud of your mandala paragraph?

• I feel proud of my paragraph because I put a lot of hard work and it was challenging which was kind of fun! - Oliver
• i feel proud of it cuz i worked really really hard on it. im proud of everything I did in my paragraph. it was really hard. im proud of my hard work. - Fatima
• I think that i am proud of myself because i tried my hardest to feel good about what i did and i feel really proud of myself now. - Effie

3. What is a topic sentence? 

• A topic sentence is a sentence that tell you what the paragraph is about - Cora
• a topic sentence is the first sentence of a paragraph and it just describes what the entire paragraph in like 5 to 10 words one of its main purpose is to hook the reader. - EF

4. What are supporting details?

• Supporting details wipe the confusion from the reader's mind. - Kaira
• supporting details are details that follow the captains order and the captain is the topic sentence so supporting details are just following the topic sentences orders and supporting details are the crew. - Viaan

Place Value

In Math these past few weeks with Ms Elder, we have been learning about the concept of Number. We have been practicing place value and Number vocabulary by: building numbers with Base Ten blocks, playing Place Value games, and doing Number Riddles.

Here are a few games we can play at home to practice:

Number Riddles

Materials: whiteboard (optional)

Instructions: 

1) One person thinks of a number (we practiced 3-digit).

2) Player 2 asks questions to get clues. Use Place Value vocabulary like: greater than, less than, odd, even, the digit in the ones/tens/hundreds place...

3) Player 1 tells them when they guess it right!

Trading Places

Materials: one set of dominoes, mat (optional)

Instructions: 

1) Flip all the dominoes upside down and shuffle.

2) Player 1 picks a domino. Choose which Place Value column you want to put that number in. Once your domino is placed, it cannot be moved.

3) Player 2 picks a domino. Repeat.

4) Player 1 picks a domino. They choose which way to put it in the Place Value columns that are left.

5) Player 2 picks a domino. Repeat.

6) Whomever has the greater number wins! You must be able to read your number out loud.

Place Value Race

Materials: one deck of cards

Instructions: 

1) Play with 2 players. Remove the 10's, Jack's, Queen's, and Kings, and Jokers. Shuffle.

2) Each player flips 2 cards over at the same time.

3) The first person to say the number out loud correctly keeps the cards. When you're finished the stack, the person with the most cards wins!

Banker's Game

Materials: one set of Base Ten blocks (could be printed or use coins), 2 dice of different colours, 1 place value mat (optional)

Instructions: 

1) Decide which colour of dice are for which place value column.

2) Player 1 rolls 2 dice. They collect the Base Ten blocks of that number.

3) Player 2 repeats.

4) Regroup when you can!

5) The first person to get to 100, wins!

Here are some pictures of us playing the Banker's Game!

.

Option: Play with 3 dice all the way to 1 000!

Reminder: Graphing Quiz on Oct 9

Students, this is a friendly reminder that you have a Graphing Assessment on Thursday, October 9. You will need to be able to: 

• Create a Bar Graph with a scale of 2:1 or higher to represent a set of data
• Accurately use the "Bar Graph Checklist" criteria used in class
• Read and interpret both Pictographs and Bar Graphs 

If you have any questions, please contact Ms Elder. If you're looking for ways to practice, there are links to games on Google Classroom.

Collecting Data through Math Games

Today, Ms Elder taught us a game called Clockominoes. In this game, you draw a domino, add the dots together, and place the domino with that total on the arm of the clock. 

We calculated as a class what the smallest number of dominoes was that you'd need to win (12), and the greatest total you'd need to win (27). We started a chart to show who in our class was the luckiest (needed the fewest dominoes to win). Then, we played to collect the data!
