1st Grade Math
Skills to Know
Counting
Practice counting objects to 100 (paper clips, pieces of cereal, blocks, anything!) by 1's and 10's
Practice writing numbers from 0 to 20
Write a numeral from 0 to 20 to represent a number of objects
Practice counting out objects (e.g., pennies) when given a number 1 to 20
Use <, >, and = symbols to show the relationship between numbers (up to 99)
Classify objects (put them in groups) and count the number of objects in each group.
Operations & Algebraic Thinking
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from
Practice making 10 when given a number from 1 to 9 by using objects or drawings
(e.g., If you have 4 paper clips, how many more do you need to make 10?)
Fluently add and subtract within 5, and solve addition and subtraction word problems.
Numbers and Operations in Base Ten
Compose and decompose numbers 11-19 to gain foundations for place value (e.g., 18 = 10+8)
Geometry
Learn the names of two and three-dimensional shapes; describe the different shapes and practice drawing them. (e.g., a square has four equal sides)
Activities to Try
Counting
Walk around your house and/or apartment. How many windows can you see? How many doors? Which object is there more of, doors or windows?
Look for 10 items in your house that can be matched with the numbers 1 through 10 (ex. 3 pots, 1 microwave, etc.). Keep a record by drawing pictures of the items you found and label each picture.
Predict how many jumping jacks you can do in 30 seconds. Test your prediction. Use the terms “less than” or “equal to” to compare your prediction and the actual count.
Operations & Algebraic Thinking
Draw a number line. Beginning with 18, go back 12 numbers. What number did you stop on?
Write ten-number sentences that equal 10. Use both addition and subtraction. Draw models to show your number sentences.
Does 6+3 = 5+2? Draw a picture to prove your answer.

Numbers & Operations in Base Ten
How many tens and ones make up the number 18? Use objects or drawings to solve. Write an equation. (e.g., 18 =10+8)
Count the number of toys that you have. Put them into groups of ten. How many tens and how many ones make up that number?
Geometry
Go on a shape hunt. Look through your house to find things shaped like a circle, square, triangle, pentagon, and hexagon. Make a chart to show your results.
Count your toys. Sort them into groups based on shape.
