Finishing up with programming

Scratch has recently released a new version of their programming adventure. This new version is online so you do not need to download to your computer. The goal of the next few classes is to get inspired by seeing what others are doing with Scratch, pick-up a few pointers about the program and launch off into the summer ready to create.

The image below shows the Scratch project screen which you will begin using today.

Start with seeing what is out there!

1. Go to the Scratch Explore Page (If you have used Scratch in the past and have a project, please send us the link!)
2. Try out different projects. What are people doing with this program?

We'll group back together in 30 minutes or so to work on a quick project.

Sprite - Can you get your sprite to move across the screen? 

Think of any game you have played on a screen. You click and things happen. Now, it is your turn to decide what will happen when clicked. Today, your goal is to experiment with motion. Can you get your sprite to cruise around the screen? We'll look at the coordinate system used in Scratch/programming.

Student created problems (unedited...)

1. It Leo's monthly pay (m) increases by $25 each month, what is the expression for it?

2. My friend and I are out on the porch the sun has set and we are are chatting into the night when a question rises. There's a light bulb above us attracting big flies, we want to know the estimated number of flies there is going to be in 9 minutes. We have been out here for 2 minutes and when we first came there were 0 flies now their are 6. If this pattern continues how many flies are there going to be?

3. The new sponge factory sold 10 sponges in each box. In the first month, They sold 20 boxes. Each sponge cost 1 dollar. 10% of the profit was used to pay a major sponsoring company. During the next few months they sold 100 sponges more of the last month. How much profit did they accumulate in the 10 months?

4. Tetsu ride her bike everyday, the first day she ride 10 mile, she increase 3 miles everyday. how many miles do she ride in the nth day?

5. The first day, Teteu read x pages of the book, second day read half of x pages of the book, the third day she read 2 times x pages of the book, how many does she read?

6. The droids are attacking the Wookie village! If each one of the Jedi's ships can hold 15 Jedi, and each ship takes 1 hour to launch, calculate the amount of Jedi in the Wookie village in 5 hours.

7. Frank wants to drive from New York to Utah, first day he drive 80 miles, second day he dive 60 miles, third day he drive 80 miles, forth day he drive 60 miles, how many miles will he drive on the fifth day?

8. 1 floor = 2 meter  A tower is 24 m high. But they are still building X floor every year. 8 year later the building crush and remain only 64 meter left.

Ratings

1. Please rate each one on an originality scale (1-5 with 5=Awesome! A text book company would want this question.)

2. Please rate each one as a math problem that models repeating patterns. (1-5 with 5 being an intricate pattern)

3. Please rate each one on its ease to be understood. (1-5 with 5 taking no effort to understand the writing and what is expected.)

Solve the problems

Looking for Mistakes

Please check Edline for current progress reports!

Today, each student should enter class with expressions that are both right and wrong. Your fellow students will use your work to explore expressions.


Working with Perimeter and Area:
You have written equations for the perimeter of the following shapes. For Tuesday, please write equations to determine the area of each shape.

Thanks to Don Steward for ideas

 Have a great weekend!

Writing Expressions & Mistakes

Today, we'll begin with a quick check-in on writing expressions. Everyone is doing a great job getting familiar with English words for mathematical operations.

Mistake Game:
You will each obtain a sheet that has the following information filled out:

• Write four (4) equivalent expressions (three correct and one wrong)
• Solve the expression, but put in a mistake
• Create three routes to get from the start to the end. One is wrong.

Your task:
1. Divide your whiteboard into three equal sections.
2. To the three tasks - one in each section of the whiteboard.
3. Check your work with me.
4. When people are finished, you will begin working on finding their mistakes.
