Preview has the capability to combine two or more pdf files into one file. Open the first pdf in Preview. Click the Thumbnails button (second button on upper right hand of screen). Open Finder, drag the second pdf that you want to add to the thumbnails side pane and release when you see the + appear. You should now see pages from both pdfs. You can reorder the pages simply by dragging them to the correct location in the side pane.
If you are posting your videos to Moodle, you may find that some of your videos are too large to post. If the video exceeds 100MB, you can choose to convert the video in Evom using medium quality instead of high. The ones I have converted using this option look and sound just as good and the files are half the size.
I wanted to post a Kuta worksheet in Moodle without the answer sheet and without having to do any scanning. So my google search led me to this link: Delete pages in a PDF document. The trick though is to change the view so that you can see the side pane that lets you select a page and delete it simply by pressing the delete key. The view buttons are on the upper right hand side of the Preview window. The second one shows the pane.
I discovered that I can create a practice quiz that students can take an unlimited amount of times using thatquiz.org. I created a class named Geometry and entered one student, named Student One. I created my practice quiz and then assigned it to that class. I clicked See Tests, then clicked on the practice test. In the upper right hand corner, there’s a link to the URL for practice only. If you click Fixed under the Order heading, it will change and scramble the questions.
The practice test I created is on special segments in triangles and their points of concurrency. I used the Slides option and used the program to draw my own diagrams. The practice test is included in my Triangles LiveBinder under the Geometry heading.
If you choose to enter your students in the class management system it will not record practice scores. I found that out it in their blog, which is very informative.
During my search to find interactive proofs, I decided to create my own in GeoGebra. I wanted something low pressure and user-friendly to ease students into proving triangles are congruent. So I scrambled the statements and reasons so students can arrange the parts to complete the proof. The proofs could also be used as a whole class activity with a SmartBoard allowing volunteers to arrange the parts. Here are the links to the first proof and the second proof. I wasn’t able to quickly add the segment notation so I left it off, reminding the students that it should be there and the statements and reasons are typically numbered.
thatquiz.org is a really cool, free website that provides interactive practice with immediate feedback for math, geography, vocabulary, and science. It allows for multiple tries if you want to set a score for the students to achieve. Each quiz has settings that can be modified to create new quizzes, so be sure to check out all the options. You can use it as is, or join for free and use their class management system.
Once you join, you can also create your own quizzes. I haven’t tried it yet, but the slide option for creating quizzes looks especially interesting. I decided not to use the class management system when I realized I would have to delete a student’s score if they wanted to retake the quiz. The multiple tries part is the best feature to me, especially since it automatically regenerates the questions. I generally give the practice as a warmup or practice after student’s have watched the lesson’s first video. As students finish, they call me over and show me their score.
I’ve included several of these quizzes in my LiveBinders. Once I select the options I want, I select Make URL and copy and paste the link into one of my LiveBinder tabs.
To create a dilation using GeoGebra, you must have a polygon and a point already drawn. Click the down arrow on the transformation tool and select dilation. Then select the polygon and point. Enter k and voila! You can enter fractions or decimals, 0<k<1, if you want a reduction.
I uploaded to Moodle a file that already had the triangle and point for the students to download. I created a handout with instructions for an enlargement and a reduction without using those words. I asked them to compare the figures and to compare the coordinates. While I was planning our next discovery, I remembered I could use the ABC text tool to type the directions in the GeoGebra screen itself. The divider can be dragged to the left to make more room. Just click where you want to type. If you need to move the text, just click on the select arrow tool then click on the text and drag where needed.
