#(text-style: "shadow")[**Welcome to GEMDAS!**]<h1>
*Instructions:
1) Have your GEMDAS reference sheet out, a pencil, and your math spiral open to a new page. You will need to turn in the paper, so make sure you show your work!
2) Select a Level to start. Make sure you read each question carefully as you evaluate the numerical expression! Consider which ''<u>blue</u>'' part of the expression you need to evaluate. You (text-style: "emboss")[gain] a point for each correct answer and (text-style: "emboss")[lose] a point for each error.
3) When you are done with a Level, continue to another Level.
4) Done? Create your own numerical expression on paper and have a partner evalute it!
5) Be ready to discuss GEMDAS with the class!*
**Select a Level to start: [[Level 1]] / [[Level 2]] / [[Level 3]]**
(set: $Points =0)
If you need to review GEMDAS before selecting a Level, watch the video below.

Refer to GEMDAS again. Remember, you may not necessarily do the first operation you see!

Since there are parentheses, which are <u>G</u>rouping symbols, you need to evaluate (5 - 2) first.

So, since (5 - 2) = 3, let's evaluate what you have so far:

4 x 3 = 12. This is what you have so far:
