|Subject Area||Math and Science|
|Unit of Instruction||Mixed numbers/Improper fractions/ Forms of energy|
|Learning Targets and Learning Criteria|
• 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.
• 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.
