Week 2 of Activities
March 31 - April 3
This week we will continue developing strategies for adding and subtracting two-digit numbers. Students will be working on being able to:
The assignments below are due by the end of this week, and the below activities are possibilities for your child to engage in to develop those addition and subtraction skills. Below the posted activities, there are links to online math games in the various math units from grade two.
- Explore and develop personal strategies for adding and subtracting one-digit and two-digit numbers
- Develop strategies to use when solving addition and subtraction problems up to two-digits
- Pose and solve a variety of number problems requiring addition or subtraction
- Understand and use the relationship between addition and subtraction to help solve subtraction problems
- Write a number as a sum or difference of two numbers

Numeracy Assignments for Week 2
To be submitted to Mrs. Barker by the end of the week
Assignment 1: Complete Two Worksheets
- As you are working on the worksheets at your level for this week, choose two of those completed worksheets to share with Mrs. Barker
- If you have access to a printer, you can print the worksheets off, but if you don't your child can answer the questions on their own piece of paper (it doesn't need to look fancy, this is just about the practice)
- It will probably be simplest for most of you to share your math answers with me by taking a picture and sending them on Seesaw or email, but send me a message if you have trouble with that and we can figure it out
Examples
Assignment 2: Show Your Strategy
- For an addition or subtraction question that you are solving this week, choose a way to show Mrs. Barker how you solved the problem
- It is important to remember that we wouldn't trust a mathematician who said, "I just knew it," or "I did it in my head"
- You can share your strategy in a format of your choosing, for example:
- A video showing your strategy (like in one of my video mini-lessons this week)
- A written description of what you did in your head or using a tool (such as "I started with 34, added the 20 from 25 to get 59, and then added the 5 from 25 to get 64" or "I started at 34 on the hundred chart, then went down two, and went right five more jumps")
- A photo of your math strategy or tool (such as the photos below)
- I am not expecting professional-level presentation whether you are submitting something written, filmed, photographed, or audio-recorded, the goal of this activity is to have students explain their mathematical thinking

Math Worksheets
When you click on these images, you can view or download the worksheets for this week. If you have access to a printer, you can print them off, but if you don't your child can answer the questions on their own piece of paper.
If your child is finding the worksheets much too challenging or much too easy, there are more or less challenging worksheets at the bottom of this week's activities (further down this page).

Video Mini-Lessons
Word Problems
Click through the presentation below to view the question and then view the answer (the students should be familiar with this format from when we answer these problems in class).
Card Games
If you click on the images below, each card links to directions to a different card game that you can play with your child (or amongst siblings) using playing cards, Uno cards, or any other cards with one-digit numbers.
Book and Activities (Optional)
Click on the book A Class-full of Projects on the left, and read it with your child. (Click here to access a PDF of the book if you can't read it online.)
As you read, encourage your child to:
Choose 1-3 of the below activities to work on with your child Try the online Make a Number activity by clicking here Race to 100: This game builds proficiency in adding and develops number sense to 100. You need a hundred chart, numeral cards for the numbers 1 to 9, and a small object for each of you, such as a coin. (Download the hundred chart and numeral cards by clicking here, or you could have your child draw their own.) Turn the numeral cards face down. To start the game, turn over 2 cards. Ask your child to help you to add the numbers on the cards. Then, starting at 1, move forward by the sum of those two cards. For example, if you pick the numbers 7 and 8, you place your marker ahead 15 more from where it was. Turn the 2 numeral cards face down again and mix up all the cards. For the next turn, your child selects another 2 numeral cards, adds those numbers, and places his/her coin forward that amount. Continue taking turns and moving your markers forward on the hundred chart by the amount of each sum. Get as close to 100 as you can! |
Make a Collection of 100: After you read, use small objects such as buttons, coins, or nuts and bolts to investigate making 100. Invite your child to grab a handful of the objects, and spill them onto a table. Have your child estimate the number of items there are. Then, invite him/her to place the items in groups of 10 (10s) and a group of the leftovers (1s). Then, ask “How many more groups of 10 do we need to make 100?”
That’s 100, Too! Look for ways to make 100, such as 50 + 50, 10 + 90, and 35 + 10 + 55. There are lots of other ways! Encourage your child to investigate other ways to make 100. You can work along, too! |
