Developing Mathematical Mindsets

Becoming a confident learner and doer of mathematics begins first with believing we are capable, that mistakes are essential to developing depth of understanding, and that most often our highest level work happens through collaboration with others.

Third Grade Mathematics Content Standards and Practice Standards

What are the mathematics concept acquisition expectations for third grade students?

Operations and Algebraic Thinking

Interprets multiplication as combining equal groups, e.g. 5 x 7 is the total number of objects in 5 groups of 7 objects each
Interprets division as separating a total number of objects into equal sized groups, e.g. 56 ÷ 8 is the number of objects in each group when 56 is broken into 8 equal groups or the number of groups when 56 is divided into groups of 8 objects each
Understands and applies mathematical properties (commutative, associative, and distributive) to multiply
Multiplies and divides within 100 using various strategies
Solves two-step word problems involving addition, subtraction, multiplication and division
Identifies and explains patterns in arithmetic

Numbers and Operation in Base Ten

Numbers and Operations -- Fractions

Measurement and Data

Solves problems involving measurement and estimation of intervals of time, liquid volume, and masses of objects
Tells and writes time to the nearest minute and measures time in intervals.
Measures and estimates liquid volume and mass of objects
Interprets data and creates a variety of graphs to represent data
Understands concepts of area and relates area to multiplication and to addition
Finds the area of rectangular shapes with whole-number side lengths using tiling, addition, and/or multiplication
Understands that an area of a shape can result in different perimeters and a given perimeter can result in different areas

Geometry

Standards for Mathematical Practice

The eight standards for mathematical practice describe the “know-how” or habits of mind that we seek to develop in students. These practices define important methods and skills that students need to be mathematically proficient.
