The Game of Tens and Ones

North Carolina Department of Public Instruction 50 min(s)

By the end of this lesson students will be able to count by tens from any given number below 100. Students will use the techniques for forming a right angle that they used in the previous lesson to create a quadrilateral with four right angles. They will use the rectangle they create to develop a class list of the attributes of rectangle that will serve as their working definition for a rectangle.
