# Q3W4 (2/16-2/19)

Weekly-Assignments-February 16- February 19 Teacher Kathleen Manning Math/Science 4 4 Multiplication of Fractions/Energy and Motion
Standard(s) Taught

MATH 4.NF.2.4

-Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

SCIENCE SC.4.P.11.1 SC.4.P.11.2

– Recognize that heat flows from a hot object to a cold object, and that heat flow may cause materials to change
temperature.
– Identify common materials that conduct heat well or poorly.

Learning Targets and Learning Criteria

The student will:
– Decompose a fraction into unit fractions and record the conclusion with a multiplication equation.
– Recognize that a fraction a/b is a multiple of 1/b.
– Recognize that a multiple of a/b is also a multiple of 1/b. (e.g. 3 groups of 2/5 has the same value as 6 groups of
1/5 and use this understanding to multiply a fraction by a whole number.)
– Investigate and diagram the direction of heat flow ( hot —> cold )
– Record observations of heat transfer (in the form of temperature changes) in tables, charts, and graphs.
– Analyze and form conclusions based on recorded observations and data.
– Review how things that give off light often give off heat.
– Review how heat is produced when two objects rub against each other.
– Investigate heat energy by measuring temperature changes in a liquid.
– Investigate which materials are the best conductors of heat (clay, metal, glass).
– Investigate which materials are non-conductors/insulators of heat (plastic, wood, styrofoam).
– Form conclusions on which materials conduct heat well or poorly based on investigations.
