Graphing/Using Linear Measurement
Unit Overview
Students demonstrate an understanding of measurement by justifying how to use tools to measure to the halves and fourths of an inch.
Students analyze and construct data using line plots and graphs. Students problem solve using properties of operations. Students add and
subtract whole numbers within 1,000. Students will understand quantities of fractions.
Length of unit: 3 weeks
KY Core Academic
Standard
3.MD.3 Draw a scaled
picture graph and a
scaled bar graph to
represent a data set with
several categories. Solve
one and two-step “how
many more” and “how
many less” problems
using information
presented in scaled bar
graphs. For example,
draw a bar graph in
which each square in the
bar graph might
represent 5 pets.
