Third grade students engage in problem solving, communication, reasoning, connecting and representing as they:

• Count, read, write, compare and order whole numbers to 10,000
• Count using 2’s, 3’s, 5’s, 10’s, 25’s, and 100’s
• Differentiate between and/or give example of even and odd numbers (limit 3 digits)
• Match a symbolic representation of numbers to appropriate whole numbers (e.g., place value blocks, 7 hundreds, 4 tens, and 8 ones, etc.)
• Use landmark numbers (10, 25, 50, 100, 1000) in combining and comparing quantities
• Demonstrate the inverse relationship between addition and subtraction using fact families
• Half and double numbers
• Solve problems involving single and double- digit addition and subtraction with regrouping
• Solve triple digit addition and subtraction problems without regrouping
• Demonstrate the concept of multiplication as repeated addition, arrays and/or skip counting
• Demonstrate a fluency in multiplication with products to 50
• Demonstrate the concept of division as repeated subtraction and as sharing
• Understand fractions as part of a whole, as part of a collection and a location on the number line
• Write the fraction that corresponds to a drawing OR create a drawing that corresponds to a fraction (numerators 1-9, denominators 2-10)
• Select and use appropriate method, materials and strategy to solve problems
• Determine the reasonableness of calculated answers
• Use estimation skills to arrive at conclusions
• Round 2-digit numbers to the nearest 10, and 3 digit numbers to the nearest 100
• Understand and use important equivalencies of time, money and linear measurement
• Count, compare, and make change using a collection of coins and one-dollar bills
• Tell time to the minute (analog and digital) and identify times of day as AM or PM
• Find elapsed time to increments of 5 minutes
• Estimate measurements of familiar objects
• Use a ruler to measure to the nearest 1/2-inch or centimeter
• Weigh with a pan balance
• Estimate, measure and compare areas by covering spaces with units and half-units
• Find the area and/or perimeter of a figure drawn on a grid
• Compare and/or order objects according to length, area or weight
• Select an appropriate unit and tool for the object being measured
• Match an object with its approximate measurement (all measurements within the same system, e.g., about how tall is a soda pop can? 5 inches, 5 feet, 5 yards, etc.).
• Identify and/or describe 2-D and 3-D objects (circle, square, rectangle, pentagon, hexagon, octagon, sphere, cone, cube, cylinder, pyramid, rectangular prism)
• Understand that shapes can be reoriented in space without losing their properties (flips, slides and turns)
• Estimate and measure the area and perimeter of various figures
• Identify/draw one line of symmetry in a two-dimensional figure
• Identify symmetrical two-dimensional shapes
• Locate points on a grid
• Identify and model right angles and right triangles using concrete objects
• Gather, organize, and display data using tables, tallies, charts, pictographs, line, bar and circle graphs and Venn diagrams
• Form and justify an opinion on whether a given statement is reasonable based on a comparison to data
• Identify the mode in a set of data
• Determine the likelihood of an event (more/most likely, less/least likely, equally likely or impossible)
• Recognize, describe or extend a variety of patterns
• Demonstrate simple function rules (input/output tables)
• Create a story to match a given combination of symbols and numbers
• Determine the missing number or symbol (+, -, =, ‹, ›) in a number sentence
