Fourth grade math students develop fluency with multiplication and division problems.  They use various models, strategies, and representations to help them in their solutions.  Also they extend their knowledge of the base-ten number system along with adding and subtracting large numbers.  They explore equivalencies among fractions.  Basic decimal concepts are also developed. In Geometry students study concepts of polygons, lines, and angles. 

     Grade 4 math instruction develops strong number concepts before introducing the traditional methods or "short cuts" of adding, subtracting, multiplying, or dividing. With this deeper understanding of how numbers work, students are more able to make connections with more complex problems and topics in later grades. 

     The fourth grade math curriculum follows the Investigations in Number, Data, and Space program with supplementation to meet the New York P-12 Common Core Learning Standards for Mathematics.  Units in fourth grade include:
