Happy Mothers' Day! The kids worked hard on your perpendicular line frames. I hope you had a great mothers' day, everyone.

You can draw perpendicular lines with a protractor. After tracing the bottom line, and drawing a dot in the center, line up the center and draw a dot at 90 degrees. Then, use the straight edge to connect the two dots. The two lines you've drawn are perpendicular.
Do you like getting packages in the mail? Have you ever thought about people's jobs in the post office? This is a simple game that lets YOU feel like you're working in a post office.
To play this post office measurement game, you need to read a ruler, scale, and table. You might need a pencil and paper, unless you can remember two different numbers for a couple minutes. Also, the measurements are metric, which means: Lengths are in centimeters Weights are in grams and kilograms We practiced connecting dots with straight lines using a ruler. This will help us in later chapters when it comes to using drawing tools for math questions.
The red line pairs that are touching are perpendicular to each other. The green lines are parallel. Can you think of another object besides a robot that has straight lines that form parallel or perpendicular line pairs? Great job to everyone who has been working hard to improve their math skills using Study Island! When you earn enough points, you unlock new games. It's a great way to study for the Math MCAS next week!
Do you need a reminder about how to use a drawing triangle to make perfectly parallel or perpendicular lines? This site will show you how: Using a Ruler and Drafting Triangle. (Click the link, not the picture). There is no sound and the animations are only about 10 seconds each, so click "play" as many times as you need to to help you practice! I'm attempting to repost a multiplication activity that worked on my own computer, but it didn't seem to work on the school computers. Here is the direct link that might not work:

Then scroll way down the page until you see an activity that looks like the picture I posted to the left in this post. http://www.dreambox.com/teachertools If you try it, post in the comments which link worked for you and which one didn't. Here's one more link that might work if the first two don't: https://play.dreambox.com/student This week during our computer time we will be using Study Island. The PTO got us this online subscription so we could practice our math skills while earning computer games!
To earn a game, you need to answer 10 questions (and get most of them right). Just like on a test, take your time to figure out the answer you feel confident about. Don't let your average be lowered by mistakes you could have easily prevented. Once you have mastered the skill, you will have a variety of games to choose from as you continue to practice. I get to see how long you have spent each day using Study Island at home (and your average score) too. This site will show you how to measure and draw angles using your protractor. http://www.mathsisfun.com/geometry/protractor-using.html The 100th day of school is this week! In 4th grade we will hold a 100 multiplication problems competition with Mr. Earls' class!
Although the first game I posted is no longer available, if you want to brush up on your 2 digit by 2 digit multiplication skills, you can practice here. It's not a game, however it is a good way to check your work as you complete each question. There's also a cute video here that can help you remember the steps. If you like turtles, you'll like this method! Here is a third way to practice, if you like to draw: lattice-multiplication Today someone requested links back to my old posts about multiplication, so here they are: 2-digit-by-2-digit-multiplication-with-area-models.html multiply-with-expanded-form-or-area-models.html 2-digit-by-2-digit-multiplication-with-zeroes.html Here is a video I created that shows you how to find the fraction of a set. (Click the link, not the picture). Remember that you can pause and go back over any parts that you need to rewatch to help you with your homework and to study for your tests.
Here is a different video on fraction of a set that I found on a Math in Focus (AKA Singapore Math) website. I didn't make it, but it shows how to use a bar model instead of circling dots. Was this video helpful? Answer in the comments below. |
