Florida State Standards for Mathematics: Grade 4
FL.MA.4.A. Algebra
MA.4.A.1. Develop quick recall of multiplication facts and related division facts and fluency with whole number multiplication.
MA.4.A.1.1. Use and describe various models for multiplication in problem-solving situations, and demonstrate recall of basic multiplication and related division facts with ease.
MA.4.A.1.2. Multiply multi-digit whole numbers through four digits fluently, demonstrating understanding of the standard algorithm, and checking for reasonableness of results, including solving real-world problems.
MA.4.A.2. Develop an understanding of decimals, including the connection between fractions and decimals.
MA.4.A.2.1. Use decimals through the thousandths place to name numbers between whole numbers.
MA.4.A.2.2. Describe decimals as an extension of the base-ten number system.
MA.4.A.2.3. Relate equivalent fractions and decimals with and without models, including locations on a number line.
MA.4.A.2.4. Compare and order decimals, and estimate fraction and decimal amounts in real-world problems.
FL.MA.4.G. Geometry
MA.4.G.3. Develop an understanding of area and determine the area of two-dimensional shapes.
MA.4.G.3.1. Describe and determine area as the number of same-sized units that cover a region in the plane, recognizing that a unit square is the standard unit for measuring area.
MA.4.G.3.2. Justify the formula for the area of the rectangle ''area = base x height.''
MA.4.G.3.3. Select and use appropriate units, both customary and metric, strategies, and measuring tools to estimate and solve real-world area problems.
FL.MA.4. Supporting Ideas
MA.4.A.4. Algebra
