By the end of the school year, all students should be able to:
■ Count to 100 by ones (1, 2, 3, …) and by tens (10, 20, 30, …). Also count to 50 by fives (5, 10, 15, …) and to 20 by twos (2, 4, 6, …).
■ Count backward from 20 by ones (20, 19, 18, …).
■ Develop an initial understanding of the base-ten system.
• 10 ones = 1 ten
• 10 tens = 1 hundred
■ Write numbers up to 100.
■ Add numbers with sums up to 10.
■ Use drawings or pictures to explain a math problem or problem-solving process. For example, show that three balloons plus four balloons plus one balloon equals eight balloons.
■ Subtract one-digit numbers. For example, 7 – 4 = 3.
■ Recognize geometric shapes and structures in the environment. For example, recognize a triangle in a Yield street sign.
■ Use objects such as paper clips or the length of your child’s foot to determine the length of a space or object. For example, count the number of paces from one side of a room to the other.
■ Identify and discuss patterns in arithmetic (what comes next in a repeating pattern, using numbers or objects). Collect and record data for a question, such as, “What is today’s temperature?”
Learning at Home
Point out how your family uses math every day. For example, when you are serving pizza or a cake, talk about how the pieces are fractions of a whole. Encourage your child to notice other examples.
Use a thermometer to determine the temperature outside your home at the same time each day or find the daily high and low temperatures on the Web or in a newspaper. Record and discuss the results.
Play board games.
Together, explore the relationships among art, color, shape, and math at the Children’s Museum of the Arts. Go to cmany.org for information and directions.
