## What your child will learn and do in Grade 2 Mathematics

In grade two, students extend their understanding of place value to the hundreds place. They use this place value understanding to solve word problems, including those involving length and other units of measure. Activities in these areas include:

• Quickly and accurately adding numbers together that total up to 100 or fewer or subtracting from numbers up through 100

• Mentally adding numbers that total 20 or fewer or subtracting numbers 20 or fewer

• Solving one- or two-step word problems by adding or subtracting numbers up through 100

• Understanding what the different digits mean in a three-digit number (place value)

• Reading, writing, comparing three-digit numbers

• Determining whether a group of objects has an odd or even number of members

• Adding and subtracting three-digit numbers based on place value

• Measuring lengths of objects in standard units such as inches and centimeters

• Solving addition and subtraction word problems involving length

• Solving problems involving money (identifying coins and their value, exchanging, solving word problems with money amounts)

• Telling time to the nearest 5-minute interval

• Collecting data, building a graph (bar graph, picture graph, or line plot) and answering questions about the data

• Breaking up a rectangle into equal-size squares and finding the number of squares using repeated addition

• Dividing circles and rectangles into halves, thirds, or fourths

• Identifying triangles, quadrilaterals, pentagons, hexagons, and cubes; drawing shapes given their number of angles or sides

Helping your child learn outside of school:

• Play math games with your child to build their fluency. For example, using a deck of cards, deal two cards and ask your child to add the two numbers before you do. Whoever says the total first, keeps the cards.

• Have your child explain the relationship between different numbers without counting. For example, 147 is 47 more than 100 and three less than 150.

• Have your child tell the time on the clock when you sit down to breakfast or dinner.

• Count change with your child. Ask them to find the change to pay the cashier at the store.

• Encourage your child to stick with it whenever a problem seems difficult.

• Can you do some easier problems and go back to this one after?

• What part of the problem is giving you trouble?

• Let's read the problem together and make sure we understand what it is asking.

• Can we draw a picture of the problem?

• Can we make up an easier problem that is similar to this? Then we can work our way up to this one.

• Let’s take a 10 minute break and come back to this one.
