There are quite a few topics to cover in third grade math! Here's an overview of what we study.
Goals: Be able to identify the value of a digit based on its place value. Represent numbers multiple ways: standard form, expanded form, place value blocks, word form. Write number words. Round numbers to the nearest hundred or ten.
Goals: Build fluency with one-digit plus one-digit addition. Represent addition multiple ways: place value blocks, number line, standard algorithm. Build accuracy adding numbers up to four digits.
Goals: Represent multiplication multiple ways: equal groups, skip counting, arrays, number sentence, repeated addition. Build fluency with multiplication tables through 10.
Goals: Build fluency with basic subtraction facts (numbers up to 20 minus a single digit). Represent subtraction multiple ways: place value blocks, number line, standard algorithm. Build accuracy subtracting numbers up to four digits.
Goals: Represent division multiple ways: equal groups, arrays, number sentence, repeated subtraction. Build fluency with multiplication/division fact families.
Goals: Represent fractions multiple ways: area model, length model, number line. Represent improper fractions multiple ways: area model, length model, number line. Recognize equivalent fractions and compare fractions based on size.
Goals: Identify and name 2D and 3D shapes. Explore rules for quadrilaterals and recognize that some shapes can have more than one label. Measure area and perimeter of rectangles and composite shapes made of rectangles.
Goals: Tell time to the minute using analog clocks. Describe times different ways: half past, quarter to, etc. Use feet, inches, and centimeters to make linear measurements. Build an understanding of measuring mass and capacity. Know common coins and bills and their value and be able to calculate a total amount.
Goals: Use picture graphs, bar graphs, and line plots to analyze data. Create line plots, bar graphs, and picture graphs to show data.
Students should be practicing math daily for at least 20 minutes. There are many ways for them to practice that counts toward their math log.
tutoring
extra math classes (Mathnasium, Russian School of Mathematics, Sylvan, etc.)
strategy or board games
online math games (This may require more frequent monitoring from adults. Check to make sure the game they choose is giving them sufficient math practice.)
gray pages in math books
iReady (preferably lessons, but the games offer math practice as well)
Students may occasionally bring home their math books to work on gray top pages for homework or complete work they didn't finish in class. We frequently review the lesson pages (purple top) in class. The answers for all pages (lessons and gray top review pages) in the math book are included in the link. Click here for the the answer keys.
Pages that are purple across the top are lesson pages that we complete in class.
Pages that have gray across the top are review pages that students can complete after finishing their lesson or work on for homework.
