# Week 22 1-29

All St. Augustine money is due THIS Friday Feb. 2nd. Please be sure to send in all money that is still due.

Math:
Understand a fraction / with a > 1 as a sum of fractions 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.
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. MAFS.4.NF.2.3

Science:
Recognize that an object in motion always changes its position and may change its direction.SC.4.P.12.1

Social Studies:
Identify explorers who came to Florida and the motivations for their expeditions. SS.4.A.3.1

Learning Targets and Learning Criteria

Math:
• 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.
E.g., 2 1/8 + 3/8 = 17/8 + 3/8 = 20/8
• 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. E.g., 3 3/4 . + 2 1/4  E.g., Students use their knowledge of decomposition (17/6 = 12/6 + 5/6 ) to calculate 17/6 – 5/6 = 12/6 .
• 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. E.g., Lindsey and Brooke need 3 3/8 feet of ribbon to design costumes for a performance. Lindsey has 11/8 and Brooke has 2 5/8 feet of ribbon. If they combine what they have, will that be enough for the project? Explain why or why not. Ribbon needed for the project 3 3/8 ft. = 8/8 ft. + 8/8 ft. + 8/8 ft.+ 3/8 ft.= 27/8 ft. Lindsey’s 9/8 ft. + Brooke’s 21/8 ft. = 30/8 ft. 30/8 ft. is greater than 27/8 ft. So they have enough ribbon for the costumes. NOTE: Denominators of given fractions are limited to: 2, 3, 4, 5, 6, 8, 10, 12, 100.

Science:
• describe an object’s position and motion in space.
• explain that motion is a change of an object’s position.
• demonstrate that moving objects always change position.
• demonstrate that moving objects may change direction.

SS:
• identify explorers who landed in Florida
• explain why explorers came to Florida and the outcome of their expeditions. Examples may include, but not be limited to, Ponce de Leon, Juan Garrido, Esteban Dorantes, Tristan de Luna
