4-5.2 Compare angle measures with referent angles of 45 degrees, 90 degrees, and 180 degrees to estimate angle measures.

Angles (elementary)

Lesson: Students learn about classifying angles by their measure and in relation to angles formed by two lines crossed by a transversal.

4-5.4 Analyze the perimeter of a polygon.

Length, Perimeter, and Area	Lesson: Introduces students to length, perimeter and area.
Perimeter (elementary)	Lesson: Students learn about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets.

4-5.5 Generate strategies to determine the area of rectangles and triangles.

Area (elementary)	Lesson: This lesson has students explore areas of rectangular and irregular shapes on a grid to help them understand the concept of area and the units in which area is measured.
Length, Perimeter, and Area	Lesson: Introduces students to length, perimeter and area.
Area Explorer	Activity: Learn the difference between perimeter and area. A shape will be automatically generated with the perimeter that you choose. Calculate the area of this shape. Area Explorer is one of the Interactivate assessment explorers.
Shape Explorer	Activity: Learn the difference between perimeter and area. A random shape will be automatically generated. Calculate the area and perimeter of this shape. Shape Explorer is one of the Interactivate assessment explorers.
Triangle Explorer	Activity: Calculate the area of a triangle drawn on a grid. Learn about areas of triangles and about the Cartesian coordinate system. Triangle Explorer is one of the Interactivate assessment explorers.

4-5.6 Apply strategies and procedures to determine the amount of elapsed time in hours and minutes within a 12-hour period, either a.m. or p.m.

Clock Arithmetic and Cryptography	Lesson: Introduces students to modular (clock) arithmetic and how modular arithmetic can be used to encode messages using simple shift, multiple and affine ciphers.
Clock Arithmetic	Activity: Work with various types of clocks in order to learn about modular arithmetic operations. Parameters: Number of hours on the clock.
Elapsed Time	Activity: Practice finding elapsed time given a starting time and an ending time. Elapsed Time is one of the Interactivate assessment explorers.
