While I no longer teach third grade math, I am leaving this resource on the page. Feel free to use these activities as review or as an extension. To develop number sense, third graders can expect to master addition and subtraction with regrouping through the thousands place, multiplication within 100, division within 100 without remainders, and rounding and comparing skills through the 1000's place.
Measurement skills students will learn this year include telling time to the minute, measuring in grams, kilograms, and liters, measuring to the nearest 1/4 inch, measuring area using multiplication and tiling, finding perimeter, and creating and analyzing bar graphs, pictographs, and line plots.
Students will also work with fractions, developing an understanding of fractions, representing fractions on a number line and with pictures, comparing fractions with like numerators and denominators, and explaining equivalent fractions.
In geometry, students will focus on the traits of 2-D shapes, including their ability to be grouped in various ways with specific labels.
