“Sir Cumference and the Great Knight of Angleland” {FREE Printable Pack!}

I am SO excited to share my newest math story activity pack! I absolutely adore the Sir Cumference books by Cindy Neuschwander. If you haven’t read them, you should check them out! They are clever and witty, and teach a variety of geometry topics in a way that is fun and engaging for kids!

If you missed it, here’s another Sir Cumference pack that I put together to explore Euler’s Formula.

This book, Sir Cumference and the Great Knight of Angleland, is a great introduction to the topic of angles, including the difference between right, acute and obtuse, as well as measuring angles.

This packet is meant to be used along with the story, so be sure to read it first! Then, there are three different math lessons you can use to go with it. Included in the download are teaching tips, as well as answer keys.

The first page is a vocabulary list, to help students explain all the new terms in their own words, as well as draw a picture as an example to keep as a reference page.

The second page is an opportunity to estimate and then measure various angles. I would suggest also letting your students look for examples of right, acute and obtuse angles around them, or maybe measure them!

The last activity allows students to use their knowledge of angles and get creative! In the story, Radius had to find his way through the labyrinth by measuring the angles, so the challenge is for students to create their own maze using only a set number of each type of angle.

For this activity, students will need graph paper, a pencil and a card with angle directions. There are two pages of cards that you will need to cut out and distribute to students that tell them how many and what kind of angles their maze should consist of. For example, if I was given the card that said, “6 right angles, 2 acute angles and 3 obtuse angles,” my maze might look like this:

I have marked the different angles (only the ones on the “correct path” count) with different colors to make it clear, but your students wouldn’t necessarily do that.

You could have them trade with a partner, and their partner would have to find their way and also count the number of each type of angle.

Or you could have students mark the correct path like I did to prove that they followed the directions on their card.

My maze is obviously not very intricate, and I did not decorate with pictures or artwork (I’m no artist…) but I would encourage students to try and make the maze a challenge and have fun with it! Especially if they are going to trade with a partner. They want to try and stump them!

I hope you enjoy these activities and are able to introduce angles in a way that is fun!

  1. So glad I found you (via the Afterschool Linky)! We are just starting the Sir Cumference books (in fact, we just did a graphing of our local park last week) so your activities are so perfect! My daughter is bumping up math classes next year so we’re doing a little pre-algebra prep over the summer.

    1. That’s great! So glad to have you! I love the Sir Cumference books, I hope you guys enjoy it! Let me know if you need any help with pre-algebra stuff! 🙂
