Don't be surprised if your third grader thinks math is fun (and don't try to convince her otherwise!). Math skills build self-esteem and a sense of mastery — essential for children this age. Your third grader may even start showing off by doing math problems in her head. Science curriculum this year is all about making predictions, experimenting, researching answers, and inventing things. The main focus is physical and environmental science — force, matter, geology, ecosystems. Here are some specific math and science milestones you can expect your third grader to hit this year. Keep in mind that educational standards vary from state to state, and even from one school district to the next. And that children develop at different rates, so your child may not do everything on this list.

In third grade, your child will learn to:

  • Count, group, and estimate. For instance, when given 100 beans, she'll be able to count them one by one, sort them into groups of five or ten, and then show how she can quickly take a shortcut and count to 100 using the groups of five or ten.
  • Read and write decimals and numbers with up to six digits, identifying the place value for each digit. For example, in the number 1,234, she will understand that 4 is in the ones place, 3 in the tens, 2 in the hundreds, and 1 in the thousands.
  • Round a whole number to the nearest ten, hundred, or thousand.
  • Understand more complicated fractions, mixed numbers (such as 2 1/2), and decimals.
  • Solve multi-step math problems.
  • Determine if the answer to a problem is reasonable
  • Understand the basics of geometry. For instance, she may observe that a square has four equal sides and four equal angles.
  • Collect, organize, and interpret data using charts.
  • Use a thermometer to measure everything from the air temperature outside to the temperature of the soil in the class garden.
  • Describe different food chains within a habitat (the sea, the forest, etc.).
  • Understand how humans affect the environment.
  • Understand how simple machines such as wheels, levers, pulleys, and screws work.
  • See the world in geologic terms — rivers, streams, mountains, oceans, lakes, plains, etc.

How the teacher will help promote these skills

To teach fractions, your child's teacher may use two square pieces of paper of equal size, one red and one blue. She'll leave the blue one whole, and cut the red one into six equal pieces and label each one 1/6. The children will then see that putting the six pieces together makes the whole. The teacher may also show your child how to use a calculator to help solve certain math problems, and present your child with math problems in a variety of forms — word problems, puzzles, etc. She'll apply math concepts to real life by introducing the idea of economics — people work to earn money, they need goods that cost X, and so on. To learn science concepts, the teacher may have your child research a food chain, for example, and write each item on a piece of paper that the children later attach to create a chain. Lessons on recycling and garbage help bring home the importance of concern for the environment. Geology lessons can start with the local area — is it mountainous, arid, farmland? Where is the nearest lake, river, ocean? How do these different formations work together?
