Q3 W24 Feb. 11th- Feb. 15th Teacher Angela Mariner Math and Science 4 24 Mixed numbers/Improper fractions/ Forms of energy
Standard(s) Taught
Learning Targets and Learning Criteria

Math

Students will:

• decompose a mixed number into a sum of fractions equal to 1 and a fraction less than 1 to find an equivalent fraction to replace the mixed number in an addition or subtraction situation.

• 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.

• 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.

• 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.

Science

Students will:

• describe the requirements/components necessary for sound to be produced.

• Investigate the production of sound (e.g., tuning forks, hollow tubes, vocal cords, or water bottles filled with different amounts of water).

• explain that sound is produced by vibrating objects.

• investigate variations in pitch (e.g., water bottle liquids, rulers, straws, stretched rubber bands).

• explain that pitch depends on the speed (fast and slow) an object vibrates and the measurements (size and length) of the object.
