2 Digit by 2 Digit Multiplication Trick



 I have decided that I want to start flipping my classroom. I know that this is a learning process, and it will take me awhile to get everything up and running. In my quest for knowledge, I discovered the website www.knowmia.com. This site is a great tool for a flipped class. This site has thousands of already recorded lesson for teachers to use in the classroom. It also has a free app for teachers to use on their iPads. The app allows you to create, record, and share videos for free! I was so excited that I decided to give this app a try over the long weekend.

The first subject in my classroom that I would like to begin flipping is math. My students have already studied multiplication, but I wanted to extend upon what we have already learned. I found a really cool math trick on Pinterest over the weekend. I found a picture of this trick, but when I clicked on the link it would not send me to where the picture came from. Unfortunately, I am not able to credit the source.

I decided to use this trick in my first attempt of creating a video for my students. I used my iPad and www.knowmia.com to create the video above. I posted a link to this video on Edmodo for my students to use. I hope that this goes well in my classroom!

Happy Teaching!

Teaching Elapsed Time

It is that time of year again! The dreadful time when I start teaching my students how to solve math problems using elapsed time. In third grade, we are just supposed to introduce the skill to our students, but with my experience in fourth grade I wanted to give my students a little more practice. This concept is always so hard for students to understand. It seems like very year I am trying to find a new way to make this skill easier for my students to understand.
This year I decided to make elapsed time a little more hands on and fun! After introducing the basics of  time, I had my students make their own clocks out of paper plates to help them show and solve different time problems. We spend time going over time to the nearest minutes and understanding time to the nearest half hour and quarter hour. Then I introduced the dreaded elapsed time. We solved a couple of problems together as a class and then I gave them some time to work on problems on their own. As a culminating activity, we played a game of Elapsed Time Bingo. I gave each student a Bingo card and displayed the problems on the Promethean Board so they could all see the problems. I also gave my student the option of using their paper clocks to help them solve the problems.

The students had a great time playing this Bingo game. I was amazed to see how much easier this difficult concept had become for them. It also gave me time to walk around the room to assess, help, and monitor students. I loved displaying the problems on the Promethean Board so I could review the answers with the students. Overall, I would say that this lesson was very effective, and I plan on using this again in the future!


Here's a sample of one of the Elapsed Time Bingo problems displayed on the board.

My students loved this game and wanted to play again! I will definitely  be using the small clue cards to set this activity up as a center in my classroom!
