Third Grade: Yearly Overview

Overview
View any or all of the segments in the 45 minute  video introduction. Third grade mathematics focuses on learning critical skills and includes lessons on number sense, computation, patterns, graphs, estimation, measurement, and geometry. Third graders will experience expanded aspects of math concepts; larger place values, more complex computations including money, 3-dimensional geometric shapes, and using estimation strategies to determine if answers make sense and are reasonable.

Overview Continued
Students will experience math activities expressing numbers greater than 1,000 in different ways, estimate to find reasonable answers, make larger money combinations, add and subtract with multiple digit numbers, and experience 2 and 3-dimensional geometric shapes. Students will gain math fact fluency in addition and subtraction to 24, read, write, and order numbers up to 100,000 in standard form, written form, and expanded form. They will discover equivalent representations of 4-digit numbers and use the commutative and associative properties of addition and subtraction.
 

Students will practice writing extended responses to problem solving situations. Students will organize and display data in a variety of formats, and they will read, interpret, and analyze the data displays. Students will tell time to 5 minutes, determine elapsed time, read a thermometer, measure with a centimeter and inch ruler, select correct tools for measuring length, weight, volume, mass, temperature, and time, and know the unit the tool measures. (ex. a scale measures pounds) Students memorize the multiplication facts 1, 2, 3, 5, 8, and 10 using arrays and charts. By March, they will learn their multiplication/division fact families up through 11.
 

Third graders will experience finding the median and mode of sets of data and work with combining matched sets with two and three elements. Addition will include four digits with regrouping. In February and March, simple fractions and decimals will be added and subtracted using pictures. All of the computation operations will be applied to whole numbers. In quarter 4 of third grade, third graders will explore and find area and volume; add and subtract decimals and common fractions with pictures; review basic multiplication facts 1 - 11; make and use coordinate systems on grids; addition and subtraction fact fluency; add and subtract 4-digit numbers with regrouping including money; understand and solve problems using appropriate computational techniques; and understand and solve problems with estimation strategies in problem solving. All of these mathematical experiences build a strong foundation for fourth grade mathematics.

Parents

You can support your third grader in mathematics by pointing out numbers larger than 1,000 in his/her surroundings; puzzles with high numbers of pieces, high scores on video games, etc. Give your child practice counting coins to higher values, adding to 18 and subtracting from 18, and noticing how 2-dimensional shapes look when they are flipped over, slid, or rotated. Have your child point out lines of symmetry in common everyday objects. These simple activities will help your child build a solid foundation for more complex mathematics concepts over time.
 

Please consider using the following suggestions to help support your child in mathematics. Practice adding coins and bills to $5.00, then subtracting amounts as well. Show how adding and subtracting are related by working with fact families: (2 + 3 = 5; 3 + 2 = 5; 5 – 3 = 2; and 5 – 2 = 3). Have your child add/subtract 2, 3, and 4 digit numbers with and without regrouping. Have your child explain what is happening in these problems in their own words. We are telling time to the nearest five minutes now! Give your child lots of opportunities to tell time to the nearest five minutes using analog and digital clocks. Show your child how to set the oven timer to an hour and 5 minutes, then have him/her practice with different times. Use the cooler weather to read outside temperatures on a thermometer. Have your child use a ruler to measure lengths with to the nearest half inch and centimeter.  All of these are no-cost, high-yield activities. Plus they are fun!

 

Your third grader is ready to really move forward in mathematics! You can support this effort by giving your child practice with multiplication and division facts through 11. Help your child understand the inverse nature of multiplication and division by working with fact families. (2 * 4 = 8; 4 * 2 = 8; 8 / 4 = 2; 8 / 2 = 4) In addition and subtraction, your child needs to practice with 4 digits and regrouping. (borrowing, carrying) Ask your child to explain their answers in words or writing. Using common denominators of 4 or less, give your child experience adding and subtracting fractions using pictures or real objects. (1/2 + 1/2 = 1; 1/3 + 1/3 = 2/3; 3/4 - 2/4 = 1/4) Use terms like certain, most likely, least likely, and impossible to strengthen probability, estimation, and reasonableness of answer. Your efforts will be rewarded with fun times shared with your child in mathematics, and with increased understanding for your child in class.

 

Consider helping your third grader prepare for fourth grade mathematics by doing these fun, no-cost activities together. As you cut up pizzas or pans of brownies, help your child understand 1/2, 1/4, 1/3, and 1/8. If children experience fractions in food, they will understand! Use the phone book or other local maps to help your child understand coordinate grids. On a trip, have your child serve as navigator. Give your child practice with the words of estimation by using words like near, close to, about, approximately. Your student will understand ball-park figures and if answers are reasonable or unrealistic. Having your child work with you determining area for home projects will help reinforce multiplication facts in arrays. Allowing your child to add and subtract amounts of money will support work with decimals and fractions. You have a great deal of opportunity to build your child's mathematical strength that will serve him/her well in middle school and beyond. Thank you!
