# Q2W7 (12/6 – 12/10) Teacher Kathleen Manning Math and Science 4 7 Problem Solving/ Law of Conservation of Matter
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
– 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.
– Represent verbal statements of multiplicative comparison as multiplication equations.
– Distinguish multiplicative comparison from additive comparison.
– Solve word problems involving multiplicative comparison.
– Solve multi-step word problems that involve multiplication and/or division using strategies for grade 4.
– Represent a multi-step word problem using equations involving a variable represented by a letter for the
unknown number.
– Interpret remainders that result from multi-step word problems.
– Explore the Law of Conservation of Mass (whole = sum of its parts) to obtain the mass of various objects
using tools and technology.
– Demonstrate that the mass of a whole object is always equal to the sum of its parts.
