SALTA 3rd grade

Utah Core Standards for Mathematics Progressions

o Use operations on fractions for this grade to solve problems from information on the line plot • Recognize volume as an attribute of solid figures and understand concepts of volume measurement. o Measure volume by counting unit cubes • Relate volume to the operations of multiplication and addition and solve real world problems involving volume o Find the volume of a right triangle by packing it with unit cubes o Apply formulas V=l x w x h and V= b x h o Recognize volume as additive o Find volume of solid figures composed of two non-overlapping right rectangular prisms • Graph points on the coordinate plane to solve real- world and mathematical problems in the first quadrant • Classify two-dimensional figures into categories based on their properties o Understand that attributes belonging to a category of two-dimensional figures belong to all subcategories • Classify two-dimensional figures in a hierarchy based on properties

• Recognize a measure of center and a measure of variation • Display numerical data in plots on a number line, including dot plots, histograms and box plots. • Summarize numerical data sets in relation to their own context

Geometry

• Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing and decomposing rectangles, triangles and other shapes • Draw polygons in the coordinate plane given coordinates for he vertices. • Find the volume of a right rectangular prism with appropriate unit fraction lengths • Apply the formulas to find volumes or rectangular prisms with fractional edge lengths • Represent three-dimensional figures using nets made up of rectangles and triangles and use the nets to find surface area
