If you don't like grading papers then Code Breakers are for you. Students will use normal distribution to draw and label a normal curve using the weight of a T-Rex. They will then answer questions ranging from simply looking at their graph to finding and looking up z-scores. The students will put their answers into boxes called "the code" for easy grading. You can also use a google form and let students insert their answers for instant grading. Once you have purchased this product, click on my profile, send me a question and include your email along with the product you purchased and I will share the Google form with you.
