# Quarter Three: Week #25th February 12th-16th Lesson Plans (Math/Science/S. Studies Homeroom Only)

Teacher Michael Lee Math/Science 4th Grade Week #25th February 12th-16th Lesson Plans Solving addition and subtraction problems involving fractions and mixed numbers/Heat
Standard(s) Taught

Math:

MAFS.4.NF.2.3 (c, d), 4.MD.2.4

Understand a fraction a/b with a > 1 as a sum of fractions 1/b.

1.      (c) Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.

2.      (d) Solve word problems involving the addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

3.      Make a line plot to display a data set of measurements in fractions of a unit (1/(2 ), 1/(4 ), 1/(8 )). Solve problems involving addition and subtraction of fractions by using information presented in line plots. For example, from a line plot find and interpret the different in length between the longest and shortest specimens in an insect collection.

Science: SC.4.P.11.2, SC.4.P.11.1

 1.      Identify common materials that conduct heat well or poorly. 2.    Recognize that heat flows from a hot object to a cold object and that heat flow may cause materials to change temperature.
Learning Targets and Learning Criteria

Math:

1. Decompose a mixed number into a sum of fractions equal to 1 and a fraction less than 1 to find and equivalent fraction to replace the mixed number in an addition or subtraction situation.
2. Find equivalent sums or differences by converting fractions greater than 1 to mixed numbers by decomposing the fraction into a sum of fractions equal to 1 and fractions less than 1.
3. Add and subtract mixed numbers with like denominators using equivalent fractions, and/or by using properties of operations and the relationship between addition and subtraction.
4. Solve word problems involving addition and subtraction of fractions and mixed numbers with like denominators using visual fraction models (i.e., circular models, rectangular models, and number line models) and/or equations.
5. Create a line plot to display measurement data including fraction units of halves, quarters, and eighths.
6. Use the measurement data on a line plot to solve problems involving the addition and subtraction of fractions with like denominators.

Science:

1. Review how things that give off light often give off heat.
2. Review how heat is produced when two objects rub against each other.
3. Investigate heat energy by measuring temperature changes in a liquid.
4. Compare observations with classmates explaining any differences that occur.
5. Collect and record temperature readings during investigations in charts, tables, and graphs.
6. Investigate which materials are the best conductors of heat (e.g., clay, metal, and glass).
7. Investigate which materials are non-conductors/insulators of heat (e.g., plastic, wood, styrofoam).
9. Form conclusions about which materials conduct heat well or poorly based on investigations.
10. Investigate and diagram the direction of heat flow (hot à cold).
11. Record observations of heat transfer (in the form of temperature changes) within tables, charts, and graphs.
12. Analyze and form conclusions based on their recorded observations and data.
