 What do I need to know about my child’s education?

Students should be able to demonstrate the following math abilities by the end of first grade. Many skills are worked on throughout the year and build on each other.

Know basic number concepts

• Count to 120 starting at any number. Read and write numbers to 120.
• Understand place value (ex. 24 is made up of 2 tens and 4 ones).
• Use the symbols for greater than (>), equal (=) and less than (<) to compare two numbers up to 100.

Add and subtract with single digit numbers

• Solve simple word problems involving adding and subtracting, like “Mary has 5 beach stones. She finds 4 more. How many beach stones does Mary have altogether?” Use objects or drawings at first.
• Write equations to represent problems, such as 5 + 4 = ?
• Know all the addition facts that add to 10 or less. Know the related subtraction facts.
• Solve addition and subtraction problems within 20 by using objects and strategies. For example, the problem “There are 15 ducks on a pond. 6 fly away. How many are left on the pond?” can be solved by counting down from 15, or by knowing how to take 5 away to get 10, then taking 1 more away to get 9.
• Solve problems where the amount that is added to or taken away is not known, such as “Tom has 7 toy cars. He gets some more for his birthday. Now he has 12 toy cars. How many did he get for his birthday?” (7 + ? = 12)

Add and subtract some two-digit numbers

• Add a two-digit number and a ten, such as 35 + 30, or a two digit number and a one-digit number such as 35 + 3 or 35 + 8, using objects and strategies.

Measurement and geometry

• Arrange three objects by length.
• Measure lengths of objects by using a smaller standard object.
• Tell and write time in hours and half-hours on digital clocks and clocks with hands.
• Make and read bar graphs to represent simple data.
• Recognize shapes (rectangles, squares, triangles) and put together several shapes to make new shapes.
