iProblemSolving is a key part of Mathematics. It helps students to deepen their understanding.
ProblemSolving Steps:
1) Listen carefully to the word problem/question and ensure they understand it.
2) Think/plan/discuss the strategies they will use to solve the problem.
3) Use appropriate strategies to solve the problem.
4) Check their work and reflect on whether their strategies worked well.
Key ProblemSolving Strategies:
a) Act it out
b) Use manipulatives (including their fingers)
c) Draw a picture
d) Look for a pattern
e) Use logical reasoning
f) Use an equation or number sentence (e.g., addition, subtraction, multiplication)
g) Guess and check
h) Make an organized list
i) Skip counting

Students in Grade 1 are expected to learn the name and value of the following coins: nickel, dime, quarter, loonie and toonie. Check out the following videos to help students learn about Canadian Money.


Once students in Grade 1 feel comfortable adding and subtracting, they can start to explore the concept of multiplication using counters, pictures of equal groups, repeated addition, skip counting, etc. Here are some multiplication videos to help their learn the multiplication facts.





What is probability? This refers to the likelihood of events happening. These are the key words: impossible, unlikely, equally likely, likely or certain. Does your child know what these words mean? Can they give you examples?
For example:
It is impossible for pigs to fly on their own.
It is unlikely to snow during the summer.
It is equally likely to get heads or tails if I flip a coin.
It is likely that I will watch television today.
It is certain that I will eat food today.
You may wish to ask your child to predict the weather.
You may also wish to engage in simple probability games such as: Rock, Paper Scissors, flipping a coin, picking a certain colour out of a box of smarties, spinner games, rolling a double, etc.
Students will also be exploring why it is important for games to be fair. This means that all players have an equal chance of winning.

We are learning about fractions of a whole: halves 1/2 and quarters 1/4. Fractions are used when a whole is divided into pieces that are equal or the same.
What can you do at home?
Have your child cut various food items such as sandwiches, cookies, etc. into halves and quarters. Then ask them explain which is bigger: 1/2 or 1/4.
Students are also learning that a numerator is the number on the top and means how many parts we have. A denominator is the number on the bottom and means how equal parts the whole is divided into.

What is mass? Students in Grade One learn to compare objects on a balance scale to identify which one is heavier and which one is lighter.
Subtraction is an important skill for students in Grade One to learn. Help your child to practice taking away through fun games such as...
1) Subtraction War Dice Game: Each player rolls a dice and subtracts the smaller number from the bigger number. Whoever answers first, gets a point. (use tally marks to keep track of the score)
2) Subtraction Domino Game: Students select two dominoes and subtracts the smaller number from the bigger number. If they are correct, they keep the dominoes. If not, they give them to the other player.
3) Subtraction War Card Game (Ace to 10no face cards): Each player turns over a card and subtracts the smaller number from the bigger number. Whoever answers first, gets both cards. The player with the most cards at the end wins. (You may want to set a timer.)

Addition and Subtraction are important operations for Grade Ones to learn. Students need to understand that plus means combining two numbers and finding the sum or total. Subtraction is the opposite operation and involves taking away a number from the total. Here is the link to a website that offers worksheets to practice addition.

Doubles is an important mental math strategy. Here is a link to a video to help students learn their doubles.



Making Tens (friendly number) is an important mental math strategy. Here is a link to a video to help students learn the numbers that make ten.

Cards are fun tools for helping students to learn about addition. Here is a game you can play at home.
Quick Draw Rules: Deal all the cards into two stacks. You may only want to use the cards from Ace (1) to 10 to make it easier. One player says "draw" and both players turn over their cards. The first player to say a correct addition sentence and sum gets to keep the cards. (or you can take turns) The winner is the player who has the most cards when the bottom of the stack is reached.
I Spy Rules: Arrange cards in rows. Player 1 secretly chooses two neighbouring cards and adds them together. He or she then says " I spy with my little eye something that makes a sum of _____." Player 2 finds and picks up the neighbouring pair or pairs with the correct sum. If player 2 misses any other pairs that make the sum, player 1 can claim them. The player with the most cards at the end wins!
Please Note: Children may need to use counters or fingers to help them add at first.

Why games? This is a fun way for students to learn and enjoy Math.
Board Game suggestions for developing early numeracy skills: Snakes and Ladders, Qwirkle, Blink, Yahtzee, Pinata, Kerfuffle, Sequence, Sleeping Queens, Patchwork, Camel Up, Number Quest, etc. Encourage children to play maths puzzles and games! Puzzles and games – anything with a dice really – will help kids enjoy maths, and develop number sense, which is critically important.  Jo Boaler Professor of math at Stanford 

A line of symmetry divides an object into 2 identical pieces. Check out the following video for an introduction to symmetry.
Can you find symmetrical objects at home or in the community? 
Grade Ones are expected to compare numbers up to 50 using the right symbols and words: greater than > , less than < and equal to =. Check out the video: Mr. Alligator Can Chomp. Here is a link to a website with worksheets students can use to practice comparing and ordering numbers.
www.k5learning.com/freemathworksheets/firstgrade1/comparingnumbers 
Place value is the term we use to talk about how numbers, when arranged in different places, have different values. If we write the number 72, we know there are 7 tens (70), and 2 ones. We are using ten rods and unit cubes to represent 2 digit numbers using base ten blocks.

It is critical that students learn to represent numbers in as many ways as they can. (e.g., manipulatives, pictures, numbers, words) Each of these representations helps students to better understand the meaning of the number. Check out the videos for examples of ways to represent numbers...

Key Measurement Vocabulary:
Length means measuring how long or short something. Area means measuring how many unit squares it takes to fill the inside of an object. Estimate means guessing how many and trying to be close. Nonstandard units means using cubes, paper clips, feet instead of centimetres or metres. 

In Grade 1, students learn to identify, create, describe and extend (what goes next) complex repeating patterns. Students make patterns with manipulatives, their bodies and drawings. The "Banana, Banana, Meatball" video is a fun way for students to practice patterns.

Subitizing is the ability to 'see' a small amount of objects and know how many there are without counting. Subitizing is an effective mental math counting strategy. Here are a couple of videos to help your child practice this skill.
Does your child have difficulty counting to 20, especially with teen numbers? Check out these videos!


Counting is very important in Grade 1. Here are a few videos to help your child practice counting forward from 1100. Don't worry if they can't do it...yet. Encourage them to keep trying and they'll get there.


Here is a link to a site that provides practice of many key concepts. At this point in the year, you may want to start with Kindergarten questions, then move to Grade 1 questions. If your child needs more of a challenge, they can try Grade 2 questions, etc.

In Grade 1, students learn that skip counting by 2s, 5s and 10s is faster and more efficient than counting by 1s. Here are some videos to help them practice this important skill. A hundreds chart is a great tool to print out and help with skip counting practice.
Students may also like to practice skip counting by 3s, 4s and 25s.
Students may also like to practice skip counting by 3s, 4s and 25s.






Does your child need to practice the concept of 10 more and 10 less? Here is a video about how to use a hundreds chart as a helpful tool.
