I begin class by putting up the answers to the unit review and have students check the work with their table group. As they are working I will go around the room and ask each group which problem(s) they had trouble with; problems that many groups found difficult are ones that I will go over with the entire class. Otherwise I will check back in with the groups and quickly help them correct their errors.
Two questions that I would like to talk about are #3 and #6b. For question #3, I want students to make the connection to what we studied in this unit. This question is in context and has a different feel to many problems we did in this unit, but it still connects to 3D coordinates and the distance formula. I will usually ask students what specific concepts we studied in this unit apply to this problem.
For question #6b, I really want students to recognize the structure of the symmetric equation of a 3D line and realize that certain values can change. It is nice to get many students to write their symmetric equations on the board and talk about what is similar and what is different about them. For example, if we look at all of the denominators we can see that they can be different, but they all have the same extended ratio.
Today we will be playing the game Lingo to help get students ready for tomorrow's assessment. I always have students work on these games without notes so that they can see how prepared they are for the assessment. Students really enjoy this game and will ask to play it again and again throughout the year. It is high energy and will get everyone involved.
The rules of the game are given in slide 2 of the PowerPoint. After the students gets a question right, I go through the question and have them explain how they got their solution. Then I go over any questions that students might have about the content.
In the video below I give instructions for how to play the Lingo round once they get the question correct.
You may choose to use math words instead of random words. I have the student who got the question correct come up to the board and write their guesses in, but the rest of their team can help them out by shouting out suggestions.
