math

Hi everyone. I hope you are doing well, continuing to learn and breathe and laugh and play.

This last week, the first graders and I had a fun zoom session in which we completed a Grid and Bear It exercise. For those of you who are working at home, I included the directions for completing the project. For this week, please:

Create your own design for a Grid and Bear It and return to me. You can include directions or I can do that for you. I would love to be able to share your designs with your current classmates and groups in future years. Try other graphing activities, such as playing the game Battleship. My father taught me how to create a game board using graph paper when I was a child. I loved it! For a gameboard you can print, click here.

Battleships

Players: Two - Also known as: Broadsides

Players take turns in trying to guess the locations of the other player's ships on a grid.

Description

Each player draws two 10 x 10 grids, labelled along the sides with letters and numbers. On the left-hand grid the player secretly draws rectangles representing their fleet of ships:

The fleet

Each player's fleet consists of the following ships:

• 1 x Aircraft carrier - 5 squares

• 1 x Battleship - 4 squares

• 1 x Cruiser - 3 squares

• 2 x Destroyers - 2 squares each

• 2 x Submarines - 1 square each

Each ship occupies a number of adjacent squares on the grid, horizontally or vertically.

Play

During play the players take turns is making a shot at the opponent, by calling out the coordinates of a square (eg D5). The opponent responds with "hit" if it hits a ship or "miss" if it misses. If the player has hit the last remaining square of a ship the opponent must announce the name of the ship; eg "You sank my battleship".

During play each player should record their opponent's shots on the left-hand grid, and their shots on the right-hand grid as "X" for a hit and "O" for a miss:

The first player to lose all their ships loses the game.

Practice Counting on a Number Line and solving the Frames and Arrows problems. Number lines are really helpful at this age for many students. Some students continue to use them as a support through 2nd or 3rd grade. This exercise is from our Everyday Math curriculum and will be revisited over the years.

Guess My Number is similar to the game Monster Squeeze from our Everyday Math curriculum apart from the fact that we play Monster Squeeze on a Giant Number Line and as a whole class activity. Play amongst your family. If you have chalk and a good outside space you can draw a number line outside to use for Guess My Number or to practice the math facts from the Counting on a Number Line worksheet.

Complete a Marilyn Burns Place Value investigation involving estimations and counting by 10s and 1s. If your amount is over 99, you can add a square for 100s.

Keep your envelope ready for our zoom session, or if you are not joining us on zoom, then follow the directions to create your own fraction kit at home. First grade curriculum can be downloaded here.

2nd graders also worked on a Grid and Graph It exercise and now each student should be at the same point in order for us to complete it next week. We were joined by Marla and practiced the cup song. We will try to learn the end of it next week. I am finding it difficult for my body and brain. I read the Dr. Seuss story, The Sneetches, to remind us to be accepting and open and not to judge by appearances. We also learned how to make fact family houses and I am hoping that the students continue to work on theirs between now and next session. The fact family house reinforces the idea of the turnaround fact 5+2=7 and 2+5=7 as well as the relationship between addition and subtraction: If 5+2=7, then 7-5=2. Also, that the 3 numbers are bound together through these four facts 5+2=7, 2+5=7, 7-5=2, 7-2=5. Students can challenge themselves through the facts that they choose, 1, 342+512=1,854 and so on.

For this week's curriculum packet, I have included two copies of the place value worksheet, a game called Reach 5,000 which reinforces column addition and place value, the next Colouring Conundrum, and colored construction paper for fraction kits. Please ensure your child has the envelope ready for our next zoom session, or if they are not participating online, follow instructions to complete at home.

Take care,
