Plane Figure: a flat, 2-dimensional shape that has length and width but no thickness or depth

Parallel: two lines that are always the same distance apart and never touch or intersect ||

Congruent: figures have the exact same shape and size ≅

The polygon family of shapes includes QUADRILATERALS. Let's make notes about some of the key vocabulary related to quadrilaterals:

Click the link below to open. Do in your work on the 12 Coordinate Planes Handout. You chose where you want to start. If you need help, get help. If someone else needs help, give help.

Check answers as you’re working. If you make a mistake, fix it.

Angle: the "space" or amount of turn between two lines that start at the same point

Vertex: the common point where the two lines meet

Perpendicular: two lines that cross each other to form a perfect "L" shape (90 degrees)

*** The base is ALWAYS perpendicular to the height.

The polygon family of shapes includes TRIANGLES. Let's make notes about some of the key vocabulary related to triangles:

On the top of the blank side, write: First name, last name, U3T3

What is the area of a triangle with a base of 11 units and a height of 7 units?

Be sure to write the formula, show your work and circle your answer.

In a trapezoid, the bases are always parallel

Today you are inventing a brand new polygon. Here are the project requirements:

1. Made up of at least one (rectangle OR parallelogram OR trapezoid) and ONE triangle -- ONLY TWO SHAPES

2. Drawn on the coordinate plane

3. All vertices clearly visible and labeled with the correct ordered pair

4. Find the perimeter (Neatly write a formula, show steps, and circle answer)

5. Calculate the area: (Neatly write two or more formulas, show steps, and circle answer)

6. Name your shape

If you need to find the distance between points on a slanted line, use this search: "What is the distance between the points (a,b) and (c,d) rounded to the tenths place"

If your work didn't demonstrate that you understood (score <3), ask for help and fix it! Resubmit ASAP.

It's time to take your projects down (that are posted in the hallway). If you want to donate it to the class, please put it in the basket. Thank you!

Yesterday's group consolidation went really well! Let's take a look at some of the work and comments that were shared:

YOU ARE THE TEACHER! Can you find the mistake?

Start by looking for one thing that the group did well.

Then, see if you can find the error or mistake that led them to come up with the wrong solution.

Unit 3 Test is Tuesday 10/21.

The test will cover everything we studied in the unit and focus mainly on T3 and T6 (the essential standards).

It will be on the computer and on paper

For each of the following, click the link to open the worksheet. Do only the assigned problems. Check answers as you work.

In your notebook, sketch each image and write the dimensions. Write the formula, and substitute to find the area. Be neat.

Parallelograms: Do 1-7 (If you're interested, try the spicy ones: 13-15)

Be sure to discuss page 181 #5

To find the distance between two positive numbers, we can subtract. If we subtract the same number from both numbers, the distance stays the same (even though both numbers shift to the left).

We can use this flexibility to avoid having to annex lots of zeros and regroup multiple times.

On the blank side, write: First name, last name, U4T1

Use the standard algorithm. Show your work. Circle your answer.

1) 0.231 + 5.8

2) 18 - 0.03

Multiplication: the process of finding the total number of items when you have an equal number of groups (e.g. 2x6 is asking how many items are in two groups of six)

Product: answer to a multiplication problem

Factor(s): numbers that are multiplied

Annex a zero means to add a zero

Trade your CYUqs for a retake.

If unprepared, open PowerSchool and review your progress. If you have a goal that is less than 3, go to Google Classroom > Classwork. Scroll down to find the student responsibilities for the unit and target you are looking for (e.g. U1T1 Student Responsibilities). Click View Instructions. Review the notes. Do the CYUQs (to a level 3 or better) and check answers as you’re working.

If your goals are all 3's or better, PLEASE go to Google Classroom and look at yesterday's CYUqs (10/30 Stu Responsibilities). I changed them (to make them "milder"). Please at least do the mild and medium questions.
