|CTE Concept(s): Describe the process of writing and executing a computer program. |
|Math Concepts: Adding Integers, Plotting points on a coordinate plane. |
|Lesson Objective: | Students will edit a Scratch story. Students will apply their understanding of the coordinate plane and Integer addition to move objects to a |
| |desired location. Students will distinguish between events and use the "change by" statements. |
|Supplies Needed: | Computer running Scratch. Access to Internet. |
|The "7 Elements" |Teacher Notes |
| |(and answer key) |
|Introduce the CTE lesson. | |
| | |
| | |
|How often do you clean your room? What do you do when you clean your room? Is it important to put things| |
|in proper place? Do you move things to the left or right? Do you move things up or down? Do you have to | |
|move things to the right and up or to the left and up? Do you move things to the left and down or to the| |
|right and down? | |
| | |
| | |
|Can you connect moving objects to the left with addition? Can you connect moving objects to the right | |
|with addition? | |
|2. Assess students’ math awareness as it relates to the CTE lesson. |Integers are negative, positive whole numbers and zero. Numbers to the left of zero are |
| |negative integers. Numbers to the right are positive integers. |
|In this lesson we learn to add integers and plot points on a coordinate plane.Do you know what are | |
|integers? What are the two kinds of integers? How do we add integers? |To find the sum of numbers with the same sign we add the numbers and keep the sign. |
| | |
|Do you know what a Coordinate Plane is? What is the "begining point" on the coordinate plane called? |To find the sum of numbers with different signs we subtract the number with smaller |
|What are the two intersecting lines that go through the origin called? What kind of integers are to the|absolute value from the number with the larger absolute value. |
|left of the origin? What kind of integers are at the right of the origin? What kinds of integers are | |
|above the origin? What kind of integers are below the origin? |The point of intersection of the two intersecting lines that run through the "begining |
| |point" of a rectangular coordinate plane is called the origin. |
| | |
| |The lines that run through the origin are called the axes. The line which runs |
| |vertically ( up and down ) is called the Y-axis. The line which runs horizontally ( left|
| |to right ) is called the X-axis. |
| | |
| |Every point in a plane has a x-coordinate and a y-coordinate. To plot a point we first |
| |move left or right and then move up or down. |
| | |
| |Some basic definitions: |
| | |
| |1. Sum: the result when numbers are added. |
| |2. Absolute Value: the measure of distance from zero. Absolute values is always |
| |positive. |
|3. Work through the math example embedded in the CTE lesson. | Scratch Programming Objectives: |
| |Scratch stage. |
| |stage background. |
| |sprites. |
| |"green flag" and "space bar" events. |
| |"goto x y" instruction |
| |"change x by" and change y by" instructions |
| | |
|4. Work through related, contextual math-in-CTE examples. | Explanation of key terminology must be provided. Students must be familiarized with |
| |key-strokes and program code to move objecrts. |
| | |
|Using the Scratch Lesson " Clean up your Room" students will: | |
|Modify the program to move objects to the desired location. |Ask students to add a new sprite of their own choosing to the room, deciding for |
|Write the coordinate of objects in the story. |themselves where it should go. |
|Write the coordinates of location where the objects should be placed | |
|Students will find the sum of integers. | |
|5. Work through traditional math examples. |The worksheets and Key to the worksheets will be provided. |
| | |
|Students will complete two sets of worksheet : | |
| | |
|Worksheet # 1: Adding Integers | |
| | |
|Worksheet # 2 Plotting points on a coordinate plane. | |
|6. Students demonstrate their understanding. | |
| | |
|Cleaning up the classroom. Starting with our IT classroom as the stage, students will | |
| | |
|1. place at least 3 items in the "wrong" location in the room | |
|2. use the "green flag" event to position each sprite in the choosen location. | |
|3. determine the coordinates of the final, "correct" position of each item. | |
|4. use the "space bar pressed" event and "change x / y by" statements to move each sprite to its final | |
|location. | |
| | |
|7. Formal assessment. |Assess the following Scratch vocabulary: |
| 1. Identify each of the following: | |
| a) The origin | |
| b) The X-axis |Stage |
| c) The Y-axis |background |
| | |
|2. Write the coordinates of each of the following points; |sprite |
|a) A ( , ) |green flag event |
|b) B ( , ) |space bar pressed event |
|c) C ( , ) |go to x y statement |
|d) D ( , ) |change x by |
|e) E ( , ) |change y by |
|f ) F ( , ) | |
|g) G ( , ) | |
|h) H ( , ) | |
| | |
|3. Find the sum: | |
| | |
|a) -7 + -4 = | |
|b) -9 + 3 = | |
|c) 7 + -5 | |
|d) 2 + 3 = | |
|e) -8 + 0 = | |
|f) -4+ -5 + 11 | |
|g) -56 + 87 = | |
|h) 45 + -36 + -94 | |
