Mathematics

Mathematics Goals:

The goal of Elementary School mathematics is to encourage students to develop strategies for problem solving, to discover answers, and to recognize patterns. The curriculum offers opportunities for the self-discovery of concepts and personal strategies as well as learning the "traditional" algorithms. Manipulatives are used at every level to provide concrete examples of abstract concepts.

In grade three, the students are encouraged to develop a conceptual, procedural, and experiential understanding of numbers and operations. Estimating and problem-solving strategies are developed toward the goal of a greater math sense and stronger computational skills. Students are encouraged to challenge answers, and to share and evaluate errors.

Texts:

Third Grade Everyday Mathematics (SRA/McGraw Hill)
Third Grade Investigations (Scott Foresman)

Materials Used:

Manipulatives, including Cuisenaire rods, chip trading, attribute blocks, geoboards, multilink cubes, 100- number boards, money (real and play); clocks; number boards; calculators; snap cubes; math decks; teacher-made and student-made counting and measuring devices.

Students who successfully complete the Grade Three Mathematics program will be able to demonstrate knowledge of:

• ability to read/write whole numbers through the millions place;
• a recall of place value;
• addition and subtraction of six-digit whole numbers, including carrying and re-naming;
• use of multiplication tables through ten;
• an ability to multiply multi-digit numbers by one-digit factors
• an ability to divide by one-digit divisors;
• the proper identification of lines, line segments, rays and polygons;
• the classification of polygons by sides and activities;
• the location of points on a grid using ordered pairs;
• the creation of artwork based on geometric concepts;
• a recall of concepts on fractions;
• the ability to compare and order fractions and mixed numbers;
• use of basic operations involving time and money; and
• a beginning knowledge of the use of graphs, statistical concepts, and probability.
