What Ontario grade 1 students learn in mathematics

Your child will be able to read and understand numbers up to 50, and know how these numbers are used in everyday life.

Your child will be able to break apart and put together numbers up to 50 using different methods and objects.

Your child will be able to compare and put in order whole numbers up to 50, understanding which numbers are bigger or smaller, in different everyday situations.

Your child will be able to guess how many items are in a group of up to 50 objects and then count them to see how close their guess was.

Your child will be able to count up to 50 by ones, twos, fives, and tens, using different objects or methods to help them.

Your child will be able to use drawings to solve problems where they need to share things equally among 2 or 4 people, even when there's a little bit left over (1 or 2 items).

Your child will be able to understand that one half of something is the same amount as two quarters of that same thing, especially when sharing fairly.

Your child will be able to use pictures to compare and put in order fractions like 1/2 or 1/4 (these are called "unit fractions" because the top number is always 1). They'll do this by imagining a whole item, like a pizza, being shared among different numbers of people, up to 10.

Your child will understand how addition and subtraction are related and use this knowledge, along with the rules of adding and subtracting, to solve math problems and check their answers.

Your child will be able to quickly remember addition problems with numbers up to 10 (like 3 + 5 = 8) and also know the related subtraction problems (like 8 - 5 = 3).

Your child will be able to add and subtract numbers up to 20 in their head, and understand how to explain the ways they figured out the answer. They will also be able to make a good guess (estimation) about what the answer might be.

Your child will be able to use objects, pictures, and number sentences to solve addition and subtraction problems with whole numbers up to 50.

Your child will be able to solve problems by sharing up to 10 items equally into groups, including groups of halves, using objects or drawings.

Your child will be able to find and talk about the repeated parts (regularities) in different patterns, including patterns they see in everyday life.

Your child will be able to make their own patterns and change them into different forms, like turning a pattern of claps into a pattern of colours.

Your child will be able to figure out the rules that patterns follow and use those rules to continue the pattern, guess what comes next, and find missing parts in patterns.

Your child will be able to make and explain patterns using numbers up to 50, showing how these numbers relate to each other.

Your child will be able to tell the difference between things that stay the same and things that can change in everyday situations.

Your child will be able to tell if two math problems, one with addition and one with subtraction, have the same answer or not.

Your child will be able to understand that different combinations of numbers can add up to the same amount, using numbers up to 50. For example, they'll know that 10 + 5 is the same as 12 + 3.

Your child will be able to solve math problems and show their work using computer code, which means writing instructions for a computer to follow. They will learn to make code that follows a step-by-step order.

Your child will be able to change existing computer code, including code that makes things happen in a specific order, and explain how those changes affect the results.

Your child will be able to group information about people or objects based on one shared characteristic and explain how they sorted them.

Your child will be able to gather information by watching things, doing simple experiments, or asking questions, focusing on one piece of information at a time. They will record this information in ways they choose and organize it using tally tables (a way to count things using marks).

Your child will be able to show information using simple graphs, like those made with real objects (concrete graphs) or pictures (pictographs). They will also learn to include a title, labels, and say where the information came from.

Your child will be able to put groups of information in order from the largest amount to the smallest amount. They will do this by looking at data shown in charts with tally marks, graphs made with objects, or pictures.

Your child will be able to look at information presented in different ways, like in charts or graphs with pictures, and understand what it means. They will also be able to ask and answer questions about this information to make good decisions.

Your child will learn to use words like "impossible," "possible," and "certain" to talk about how likely something is to happen, and use this understanding to make guesses and smart choices.

Your child will be able to guess and check if the way things are grouped in one set of information will be the same in another set of information of the same size.

Your child will be able to sort 3D objects (like a ball or a box) and 2D shapes (like a circle or a square) based on one feature, such as color or size, and figure out the rule used for sorting.

Your child will be able to build 3D shapes and find 2D shapes (like squares or circles) within those objects or other things around them.

Your child will be able to build and talk about 2D shapes (like a square) and 3D objects (like a cube) that can be cut or folded exactly in half.

Your child will be able to describe where things are in relation to other things (their "relative location") using words like "beside," "above," or "under" (this is called "positional language").

Your child will be able to give and follow directions to move from one place to another.

Your child will be able to point out things that can be measured in 2D shapes (like a drawing of a square) and 3D objects (like a block), such as length, the amount of space something takes up (area), how heavy something is (mass), how much something can hold (capacity), and the space between two lines that meet (angle).

Your child will be able to compare different objects and put them in order based on their length, how much space they cover (area), how heavy they are (mass), and how much they can hold (capacity).

Your child will be able to read a calendar and use it to find specific days, weeks, and months, as well as holidays and the different seasons of the year.

Your child will be able to recognize Canadian money, including coins up to 50 cents and bills up to $50. They will also understand which coins and bills are worth more than others.
