Day 5 of Cesi’s 10 days of Christmas and today we bring you some festive coding:

1.      The Grinch Hour of Code- https://www.grinchhourofcode.com/game.html

🎄No need to login or sign up

🎄Lovely way to introduce students of all ages to block Coding: "Help the Grinch return all the presents he stole from the residents of Whoville". 

2.      Code with Anna and Elsa- Code.Org

We include this every year- Code.Org’s  Code with Anna and Elsa: https://studio.code.org/s/frozen/lessons/1/levels/1 

🎄Great for this time of year- and many teachers new to CS may not have used it before. This one is all about drawing snowflakes in the Ice. 

🎄Great for Maths- learning about angles and actually does get quite difficult.

🎄Plus with the sound of Elsa's skates on the ice is sooo Christmassy

CESI’s  10 Days of Christmas 

Day 7 and Day 8 of Cesi’s 10 days of Christmas - just because 😁 

Lots of people loving Day 3's challenges so we are powering up the frustration levels with two more: 

Day 7

https://little-dot.toxicode.fr/

🎄this one is definitely a step up 

🎄using the arrows and space bar on the keyboard, you have to follow the instructions to unlock each level.

Day 8

This is for all wannabe number crunchers- It is similar to countdown if anyone is familiar with that- video here: https://youtu.be/_JQYYz92-Uk?si=O-WvY1E2nJIllvgm&t=7

🎄You have to work out how to get from one number to another

🎄Great brain training for those of us who might need it and would be amazing as a starter or finisher activity in a classroom. 

🎄I am keeping this one for my first class back in January- will defo get their brains working again! 🎁🎅🎉.
