Students work with numbers up to 1,000 and learn how to break down numbers in different ways. For example, how the number 225 can be described as 200 + 20 + 5 or 2 hundreds, 2 tens, and 5 ones. Students learn that fractions can be represented in more than one way – for example, one-half can be thought of as two one-fourths. Multiplication is introduced using rows and columns, and students are expected to know x 2, x 5 and x 10.
Students learn to identify and describe what repeats in a pattern, such as when a specific event happens every Monday, or when a number sequence goes up by 2 each time. Students begin to identify multiplication and division equations that are equal, such as 3 × 4 and 6 × 2. Students will write code to perform a repeating operation, such as a repeating number pattern. They will also use mathematical modelling to analyze and create possible solutions for real-life situations, such as raising funds for a charity.
Students continue to develop their understanding of data. They learn more ways to collect, organize, display and interpret data involving larger numbers. They start to use scales on their graphs so they can represent larger data collections and use averages to make comparisons of data.
Students continue to develop their spatial sense as they recognize and describe three-dimensional objects and imagine what these objects would look like if they were taken apart or flipped around. Students continue to measure length and are introduced to measuring the weight of an object or how much it holds. They measure area and compare it to length, as well as learn how to tell time on both digital and analog clocks.
Students continue to develop their understanding of money by calculating the change required for simple transactions involving whole-dollar amounts.
Social emotional learning skills and mathematical processes
Students identify and learn to manage emotions that they may feel such as pride, confusion, fear and excitement. For example, in algebra as they create and execute code that represents a mathematical situation.
