Measuring Angles

• 4.7C determine the approximate measures of angles in degrees to the nearest whole number using a protractor; – R RC3
• 4.7A illustrate the measure of an angle as the part of a circle whose center is at the vertex of the angle that is “cut out” by the rays of the angle. Angle measures are limited to whole numbers; – NT
• 4.7B illustrate degrees as the units used to measure an angle, where 1/360 of any circle is one degree and an angle that “cuts” n/360 out of any circle whose center is at the angle’s vertex has a measure of n degrees. Angle measures are limited to whole numbers; – NT
• 4.7D draw an angle with a given measure; – S RC3
• 4.7E determine the measure of an unknown angle formed by two non-overlapping adjacent angles given one or both angle measures. – S RC3 [including complementary and supplementary angles]

Measurement Conversions Using Tables

• 4.8B convert measurements within the same measurement system, customary or metric, from a smaller unit into a larger unit or a larger unit into a smaller unit when given other equivalent measures represented in a table; – S RC35.7 solve problems by calculating conversions within a measurement system, customary or metric S

Solve Measurement Problems

• 4.8C solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate R

Multiplication and Division with Decimals and Whole Numbers – Computation

• 5.3D represent multiplication of decimals with products to the hundredths using objects and pictorial models, including area models S
• 5.3E solve for products of decimals to the hundredths, including situations involving money, using strategies based on place-value understandings, properties of operations, and the relationship to the multiplication of whole numbers R
• 5.3F represent quotients of decimals to the hundredths, up to four-digit dividends and two-digit whole number divisors, using objects and pictorial models, including area models S
• 5.3G solve for quotients of decimals to the hundredths, up to four-digit dividends and two-digit whole number divisors, using strategies and algorithms, including the standard algorithm R

Reviewing Problem Solving with Area and Perimeter

• Measuring Area of Rectangles with Unit Squares – Connecting Multiplication
• 3.6C determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row; – R RC3
• 3.6D decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area; and – S RC3
• Measuring Perimeter
• 3.7B determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems; – R RC3
