3rd grade Math
Course Description
Students in 3rd grade will focus on
developing understanding of multiplication and division and strategies for multiplication and division within 100;
developing understanding of fractions as numbers on a number line in order to sequence and compare fractions;
developing place value understanding in order to add, subtract and round numbers to 1,000; and
describing attributes of two-dimensional shapes in relation to finding area and perimeter of a given shape.
Quarter 1
Summary:
Students will interpret products and quotients of whole numbers using multiple strategies to solve two-step problems.
Learning Targets:
I can interpret products of whole numbers, 1-5. OA.1
I can interpret whole-number quotients of whole numbers. OA.2
I can apply properties of operations as strategies to multiply and divide. OA.5
I can understand division as an unknown-factor problem. OA.6
Quarter 2
Summary:
Students will fluently add, subtract and round numbers up to 1000 using knowledge of place value and properties of operation to assess reasonableness.
Learning Targets:
I can solve two-step word problems using the four operations. OA.8
I can represent problems using equations with a letter standing for the unknown quantity. OA.8
I can assess the reasonableness of answers using mental computation and estimation strategies including rounding. OA.8
I can fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. NBT.2
I can interpret products of whole numbers, 6-9. OA.1
Quarter 3
Summary:
Students will understand fractions as equal parts of a whole and use a number line to determine equivalence and compare size.
Learning Targets:
I can understand a unit fraction, 1/b, is formed by 1 part when a whole, b, is broken into equal parts, and unit fractions can be combined to form larger fractions. NF.1
I can understand a fraction as a number on the number line; represent fractions on a number line. NF.2
I can explain equivalence of fractions and compare fractions by reasoning about their size. NF.3
I can partition shapes into parts with equal areas.
I can express the area of each part as a unit fraction of the whole. G.2
Quarter 4
Summary:
Students will determine the attributes of polygons in relation to finding area and perimeter.
Learning Targets:
I can relate area to the operations of multiplication and addition. MD.7
I can partition shapes into parts with equal areas and express the area of each part as a unit fraction of the whole. G.2
