MA 3.1 Students will communicate number sense concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.3.1.1 Students will demonstrate, represent, and show relationships among whole numbers and simple fractions within the base-ten number system.
MA 3.1.1.a Read, write and demonstrate multiple equivalent representations for numbers up to 100,000 using objects, visual representations, including standard form, word form, expanded form, and expanded notation.
MA 3.1.1.b Compare whole numbers through the hundred thousands and represent the comparisons using the symbols >, < or =.
MA 3.1.1.c Round a whole number to the tens or hundreds place, using place value understanding or a visual representation.
MA 3.1.2.b Select and apply the appropriate methods of computation when solving one- and two- step addition and subtraction problems with four-digit whole numbers through the thousands (e.g., visual representations, mental computation, paper-pencil).
MA 3.1.2.c Use drawings, words, arrays, symbols, repeated addition, equal groups, and number lines to explain the meaning of multiplication.
MA 3.1.2.d Use words and symbols to explain the meaning of the Zero Property and Identity Property of multiplication.
MA 3.1.2.e Multiply one digit whole numbers by multiples of 10 in the range of 10 to 90.
MA 3.2.1.b Interpret a multiplication equation as equal groups (e.g., interpret 4 × 6 as the total number of objects in four groups of six objects each). Represent verbal statements of equal groups as multiplication equations.
MA 3.3.2 Students will determine location, orientation, and relationships on the coordinate plane.
No additional indicator(s) at this level. Mastery is expected at previous grade levels.
MA 3.3.3 Students will perform and compare measurements and apply formulas.
MA 3.3.3.a Find the perimeter of polygons given the side lengths, and find an unknown side length.
MA 3.3.3.b Tell and write time to the minute using both analog and digital clocks.
MA 3.3.3.c Solve real-world problems involving addition and subtraction of time intervals and find elapsed time.
MA 3.3.3.d Identify and use the appropriate tools and units of measurement, both customary and metric, to solve real-world problems involving length, weight, mass, liquid volume, and capacity (within the same system and unit).
MA 3.3.3.e Estimate and measure length to the nearest half inch, quarter inch, and centimeter.
MA 3.3.3.f Use concrete and pictorial models to measure areas in square units by counting square units.
