Standard(s) Taught

MATH: MAFS.4.OA.1.1 MAFS.4.OA.1.2 MAFS.4.A.1.3

– Interpret a multiplication equation as a comparison.
– Represent verbal statements of multiplicative comparisons as multiplication equations.
– Multiply or divide to solve word problems involving multiplicative comparison by using drawings and equations
with a symbol for the unknown number to represent the problem distinguishing multiplicative comparison from a
additive comparison.
– Solve multistep word problems posed with whole numbers and having whole number answers using the four
operations, including problems in which remainders must be interpreted.
– Represent problems using equations with a letter standing for the unknown quantity.

SCIENCE: SC.4.P.8.3

– Explore the Law of Conservation of Mass by demonstrating that the mass of a whole object is always the same
as the sum of the masses of its parts.

Learning Targets and Learning Criteria

The student will:

– Interpret a basic multiplication equation as a comparison.
