Last week we learnt about the Viking alphabet, Runes. We made a stave and found that every letter of the viking alphabet could be made using one of these as a guide. The straight lines, angles and triangles made me think that there could be a maths lesson in there somewhere. I had just ordered some geoboards as recommended by Phyllis at All Things Beautiful and decided to make a stave using the board and similar coloured elastic bands:

I had the children, for fun, experiment making some of the Viking letters. My guys have never used a geoboard before, so this gave them practice before starting our maths lesson:

I did as I had done before and typed up a maths quest sheet. This time the geometric maths concepts included the different types of angles found and the various triangles which exist with the angle and side rules associated with each one:

We used the sheet of runes to measure some of the angles made within each letter. I taught the children the types of angles and had them write which type of angle the chosen angle was in each letter. T10 understood immediately. The girls needed to be walked through it a few times, but eventually understood. We had a chat about where we could find angles in life and they all came up with many examples. T10 mentioned that by using the elbow joint he could make four of the angles. This gave me an idea for consolidating the information for the girls. I had them stand up and we played Simon says with angles (i.e. ‘Simon says make an acute angle…) You wouldn’t know it by their faces but they had a ball. Maybe they were concentrating…

I asked how they might make a reflex angle. Try as they might they couldn’t make that joint go backwards! So I asked them to figure a way, using their bodies, to make a reflex angle. This is what they came up with:

Not bad!! We moved onto triangles. L9 immediately knew why they were called triangles. I asked them to look at each picture and determine what the rule was. For example- what is it that makes an Isosceles triangle an Isosceles. With much prompting they soon figured that an Isosceles triangle had two sides the same length and two angles the same. After that they understood what was expected from them and flew through the others.

They had fun finding the triangles in the letters and figuring the type of triangle. One of the girls made the link between the angles already worked out previously and the name of the triangle. They took turns finding different triangles using the stave (not many!) and finally I had them use Cusiniere rods to recreate the runes, ensuring the triangles and proportions and angles were fairly accurate. They had to write one word, which I had to decipher:

This was fairly successful and they definitely enjoy it more than sheet maths. I don’t think angles are solid in their minds yet so in a couple of weeks I’ll revisit and see how much they have remembered and do another teaching session incorporating Pythagoras’ Theorem.

Are you allowed to have that much fun in school? Very inventive.

Sure we are! You know, you’re still not getting your peddles until Christmas, no matter how complimentary you are!!!!

Simon says to learn angles-what a great idea.

Simon and what he says plays a large part in our school life!! The children learnt all the body organs that way when they were younger!

I knew you would have a ball with hands-on math. Be careful… you might get to like it too much! 🙂

I think I’m better at teaching maths I’ve planned out myself, but the time it takes…..well, I still think a couple more hours in each day would be great!

I love showing the angles with your hands!

Hopefully they’ll never forget it!

Fun Stuff!! I guess we have to play Simon Says today:) Thank you for sharing.

I’m laughing! I have visions of homeschoolers up and down the world playing Simon says…!
