Summary

I began by teaching you about operators and operands in general. I also taught you about expressions and statements. I gave a very briefintroduction to type.

I presented and explained a sample Scratch program that illustrates how to use arithmetic operators in Scratch.

Finally, I provided the specifications for a student-programming project for you to write in order to demonstrate your understanding of what you learned fromthe first program.

Copies of both programs have been posted online for your review (see Resources for the URL) . If you don't find the program using that URL, search the Scratch site for the usernamed dbal.
