4th Grade Measurement and Data Summary
Summary:
In fourth grade measurement and data students begin by applying the area and perimeter
formulas of rectangles in real world and mathematical problems. Students need to
understand and communicate why these formulas work.
Students will learn to use line plots and display data in measurements of fractions of a
unit. They can solve addition and subtraction problems using the data in a line plot.
Students will recognize angles as geometric shapes that are formed wherever two
rays share a common endpoint. They will begin to understand concepts of angle
measurements.
Students will measure angles in whole-number degrees using a protractor.
Lastly, fourth graders will recognize angles measurements in parts (perpendicular, equal
angles) and be able to find the measure of missing angles.
Materials:
Materials for area and perimeter would be rulers. This is necessary in order to measure
the length and width of a rectangle (or any shape) correctly.
Materials for line plots might include a ruler to make a straight line for the line plot on
paper, and manipulative for the items being recorded. These might include blocks, cubes,
washers, chips, M&M’s, etc. In order to make fractions, teachers may want to use items
that can be broken apart such as square blocks for whole numbers and triangles for half’s.
All of these would help give a visual of what is being measured on a line plot.
To form angles and rays students would want to use protractors and rulers. This is useful
to students when forming an angle with the correct measurement and making the lines
straight. Students could use creative objects to create angles and form rays. These objects
might include pencils, crayons, paper, etc. (anything with a straight edge that can be
formed into an angle connected at the endpoints.)
Students will need protractors in order to measure angles in whole-number degrees. This
will be used to help students measure to the correct degree accurately.
Students will need protractors for recognizing angles and missing angles. This will helps
students be accurate in measuring angles and understand how the measure corresponds
to the size of the angle. This will in turn help the students accurately add or subtract the
angles to find missing angles and compare their findings.
