In this Sir Cumference story, Sir Cumference and the Great Knights of Angleland, Radius must prove himself on his quest for knighthood by rescuing a king. Sent off with the family medallion for luck, Radius dodges dangers and dragons. The ultimate challenge lies in a mysterious castle with a maze of many angles.

### Sir Cumference and the Great Knights of Angleland Unit Study Lessons

Here are a few of the lessons you will find in this Sir Cumference and the Great Knights of Angleland unit study:

Angles
If two lines intersect, they form angles. The spaces between the lines are angles. Have your child show you the angles.

Another way of looking at angles is to say that two rays sharing the same endpoint is an angle. (Diagrams are included in the unit study.)

Protractor
A protractor is a measuring device for measuring angles. The unit of measure on a protractor is a degree.

Practice drawing some angles. Here are some instructions on how to use a protractor to draw angles.

• Draw a straight line (i.e. an arm of the angle).
• Place a dot at one end of the arm. This dot represents the vertex of the angle.
• Place the center of the protractor at the vertex dot and the baseline of the protractor along the
• arm of the angle.
• Find the required angle on the scale and then mark a small dot at the edge of the protractor.
• Join the small dot to the vertex with a ruler to form the second arm of the angle.

Parallel Lines
In the book are a pair of dragons that belong to King Lell. They are referred to as a “Pair of Lells.” They eventually create parallel lines when they stretch across the moat to become a living drawbridge for people to enter the castle. Does your child know what parallel means? Parallel means that the lines run beside each other but are positioned so that they will never run into each other (intersect each other).

Using two rulers or yardsticks place them on the floor apart from each other….can you child decide if they are parallel or not? He/she may have to imagine the lines continuing from each end…will the lines eventually meet? If they will then they are not parallel. You could also do this activity on a geoboard.

Create different lines on the board with the bands, which ones are parallel?
