Prior Knowledge: Students will use basic knowledge of multiplication facts, power of 10, multiplication.
MathBlast 16 Number of the Day
Math Blast is a quick, fun, fastpaced math game! Every day starts with a Number of the Day. This is the tool I use to not only recall, reteach and preteach but it is my way to start classroom management. Students know the expectations of how to come in and get right to work. I do not have to spend any time waiting for students to get ready. Class starts immediately. And since I include music students are really engaged. I also encourage students to support each other for those struggling learners. This is also a great vehicle to expose students to concepts that I know will show up in state testing so that when we do get to these lessons students have already seen the work. Math Blast’s progression goes from easy to hard on the difficulty scale!
Students use a white board and divide it up as follows:
This space students write in the number of the day.

This section is the factors of the number of the day. 
This section the students put the number of the day over 100.

This section students write if the number is Prime, Composite or Square. 
Using the fraction, students write it as a decimal and a percentage. 
This section the students put the above fraction in Lowest Terms if possible.

I end Math Blast and lead into my lesson with a See, Think, Wonder. The art is choose always relates to the unit I am teaching. It is a real fun way to get your students to think deeper about a subject without them knowing that they are doing it.
The SEE part is pretty basic thinking, I see….
The THINK part gets them thinking a little deeper. This art makes me think about….
And the WONDER gets them really thinking deeper. This art makes me wonder if…. It is my way to getting their brains ready to think about math and I find that the transition is great. It is also a quick chance to expose my students to different types of art.
Note: You don’t have to use art. I use art because I am passionate about art. Use
examples of things that ignite your passion!
Concept: rounding to the nearest 10s, 100s, 1000s to estimate is a tool that adults use in the real world. Use a real world problem to show how and why we use estimation in simplify our lives.
Script, if needed: Before I became a teacher, while I took a break from designing clothing I worked as a muralist. I would be hired by interior designers to go into homes to paint murals in dining rooms, bathrooms, kids rooms…you name it. But before I would go and do the job I would have to submit a bid to see if they people wanted me to start the work. But trying to exact bids is a lot of work so I would estimate how much job would cost. I used a chart like this:
See payment/charge form to show students how this would work.
Give students three projects to price out:
Have a discussion about why we would estimate and when we think it would be a good tool to use? When would you not use estimation?
The Closing It section of the lesson is very important. This opportunity allows you to bring the class back together and have them make the connection to the learning objective of the day. You should also make sure that you make a connection to the word of the day. This closing gives students the opportunity to make the connection to the launch and they work that they did. It is also another chance to give a quick formative assessment to check for understanding.
The PostIt Poster: 2354 x 21, 2354 x 210, and 2354 x 2100. Estimate and multiple!
The Quick Assessment is supposed to be quick and on the easy to medium difficulty level. You are checking to see if students understand the basic concept of the lesson. If you make the problem difficult you are adding a different level of assessment. If you are teaching a higher level class adding a difficult layer might be appropriate but please note that I do not find it necessary to add this level.
