Weeks 1 & 2 
Multiplying Fractions by whole numbers
   CCSS.MATH.CONTENT.4.NF.B.4
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

Week 3 
Making and interpreting line graphs and line plots 
CCSS.MATH.CONTENT.4.MD.B.4
   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 difference in length between the longest and shortest specimens in an insect collection.

Week 4 & 5
Metric measurement and customary units of length, weight, and capacity
CCSS.MATH.CONTENT.4.MD.A.1
   Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. 
CCSS.MATH.CONTENT.4.MD.A.2
   Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

Week 6 & 7
Area and Perimeter 
CCSS.MATH.CONTENT.4.MD.A.3
Apply the area and perimeter formulas for rectangles in real world and mathematical problems. 

Weeks 8 & 9
Tenths, hundredths, expressing decimals as fractions, comparing decimals
CCSS.MATH.CONTENT.4.NF.C.6
   Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
CCSS.MATH.CONTENT.4.NF.C.7
   Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
