Thank you so much!!! You have saved my buns for my final days of the year review.
My students LOVED this problem. Now they are begging for more! Big thumbs up!
I'm going to use this with my high school computer class as an Excel, database project. They can use the computer as a tool to decode. Can't wait to try it!
Lovely concept and variety of mathematical/logic skills
This is so awesome I worked this with my son and it became a family fun .. He being the leader of-course ;)
Thank you :)
This was really useful thanks. Are there any cited standards for this lesson?
Very good - one suggestion. Could you provide a little more direction for Clue 5 for this teacher... I didn't have time to work through the entire activity.
Hi Carol,
I've used this type of code in previous lessons with students. Look at MNO on the complete map. It is in a four-sided box. So if you see a four-sided box in the code, you know that the letter must be either M, N, or O. If the dot is on the left of the four-sided box, the letter is M. If the dot is in the middle of the four-sided box, the letter is N. If the dot is on the right of the four-sided box, the letter is O. All boxes can be compared with the complete map. Whichever lines are missing will correlate with the similar box on the complete map. Once the students get the hang of it, they really enjoy it!
My 7th grade math classes LOVED this!!!!! Very engaging!!! Thank you so much
They didn't even realise they were doing math. They all completed theb first part fairly quickly which meant that they were well on their way when the tasks became more difficult. Sound psychology!
