Mathematics in Grade 1
In grade 1, students start thinking more about numbers and counting as concepts instead of just counting by rote. They learn about the place value number system — for example, whether a number stands for ones, tens, or hundreds, as in the numbers 2 (2 ones), 20 (2 tens), or 200 (2 hundreds).
Students continue to gain skills in adding and subtracting and can easily add and subtract small numbers. They use simple units of measurements, such as inches and cups, and can locate objects in space (for example, the chair is next to the door or the hat is on the hook). They use simple charts and graphs to represent and compare data.
TOPICS COVERED
Expectations for what a child should be able to do increase from one grade to the next. Expectations are:
• Understanding numbers and how they work, such as adding, subtracting, multiplying, and dividing (Number Sense and Operations)
• Investigating patterns and using symbols (such as x + y = z) to analyze mathematical situations and change (Patterns, Relations, and Algebra)
• Identifying shapes, sizes, and relationships (Geometry)
• Using number relationships to find out size and volume (Measurement)
• Doing experiments, collecting data, and using the information to decide what will happen (Data Analysis, Statistics, and Probability)
WHAT YOUR CHILD SHOULD KNOW
BY THE END OF GRADE 1, YOUR CHILD SHOULD KNOW AND BE ABLE TO PERFORM THESE SKILLS:
1. Count, read, and write whole numbers to 100 and relate them to the amounts they represent. For example, know that 60 is bigger than 20.
2. Compare and order whole numbers to 100 by using symbols for less than (<), equal to (=), or greater than (>).
3. Know and remember addition and subtraction facts for numbers up to 10. Use these facts to solve problems.
4. Add and subtract one- and two-digit numbers without regrouping them. For example, 12 + 2 =?; 14 - 2 =?
5. Describe and create addition and subtraction number progressions. For example, 1, 3, 5, 7 … is the result of adding 2 to the previous number.
6. Skip-count forward and backward by twos, fives, and tens up to at least 50.
7. Identify symmetry in two-dimensional shapes (for example, when two sides of a triangle are the same).
8. Observe two or more different objects, comparing their lengths, weights, and volumes.
9. Use charts, pictures, and bar graphs to represent and compare data. For example, put a star on a chart every time the child helps make his/her lunch. Are the number of stars about the same each week, or are there big differences?
HOME ACTIVITIES
1. Line up bowls of different sizes. Ask your child to decide which one will hold the most water.
2. Count the windows in your home. Ask your child what twice that many would be. Half that many?
3. Help your child use scissors to cut out different geometric shapes, such as a rectangle, circle, and triangle. What happens when you cut each shape in half or in quarters?
4. Together, turn to a page in a book and find its number. Ask your child to think of other numbers. Are they higher or lower than the page number? Find the pages that match your child’s numbers.
5. Explore time, money, number sense, geometry on the Inernet with your child.
