Exposing Kids To 10 Hours Of Science A Year Makes Them Smarter

Low-income minority fourth-graders from south L.A. improved their test scores in math and language after they got just a handful of science lessons, a new study found. College students studying science presented 10 separate one-hour lessons, and the kids rose up whole percentile ranks in other subjects.
“A lot of students say things like, ‘I didn’t know science was fun,’” said Samantha Gizerian, now a clinical assistant professor at Washington State University. Apparently they also showed a greater interest in taking books home to read, and a greater willingness to practice math. The lessons were simple, too—in one case, a college student just brought in some microscope slides from his lab.

Once I introduce the wood blocks, I am going to put a “photo book” of things to do in the block center. It will look something like this, but instead will be one of those cheap albums you can find in the dollar store in order to save space.

I got this cheap Checkers board at the Target dollar spot for $2.50.  I had been trying to think of another game to have in my classroom that facilitated strategy and academics.  You play the game same as you would play Checkers. Every time they move a checker piece to a square, they they have to do what that square says.  On the brown squares, students will have to remember word sounds or rhyming every time move their checker piece.  On the yellow spots, they answer the math question each time they move their piece to a specific spot.  It’s similar to Math Jenga

Oh, what a little GENIUS, you are!

I have a cheap checkers board sitting in my living room right now. YES.

I’m really loving this idea.  Could also be a vocab game.

Idroo: Online Educational Whiteboard

This is a free tool that can be used by multiple users at once, and can even used with Skype.  There are math typing tools and other images to enhance learning.  I think this would be a good way for schools to provide homework help or extra tutoring — and not directly after school.  

Could you see yourself using this tool?  How so?

Back, Back, Back It Up — Math Tricks

My students that come to me for math on Mondays, usually understand the material by the time they take their tests.  However, they often make simple mistakes which lowers their grades.

With multiplying double digit numbers, they had 3 common mistakes.

The first was carrying the wrong number.

PPT’s Solution:   The number in the back of the line goes on the bottom.  So if they multiply 29x32, and they start with 2x9= 18, the 8 is in the back of the line and it goes on the bottom and they carry the 1.

The second was adding a number that they carried in twice.   This would happen, for example with the above problem, when they multiplied 3x2, they would add in the 1 from the 18 they had when they multiplied the one’s place numbers.

PPT’s Solution:  After you’ve added a number that you carried, cross it out so you remember that you used it.   It will still be there for you if you check your work.

The third mistake was less common.   When moving to the 3x29, some students forgot to put their 0 before multiplying (since the 3 really represents 30).  

PPT’s Solution:  Leave some space under the equal line, and put the 0 on the second row (where you would do the 3x29 part) in before you do any multiplying.

They understood why they needed the zero, but they occasionally forgot it.

I also told them they could write “Back on the bottom” on their tests.  I’m looking forward to seeing their grades after their classroom teacher grades it.

Create a Graph

With this site you can create bar, line, area, pie, and xy graphs.

I used this when I taught K-1 on my smart board to make bar graphs as a class on things like favorite colors, favorite holidays, what color shirt students were wearing, etc.  I also had it book marked as one of the activities that students could do in the computer center.

Amble Web Function Machine

I know that Everyday Math has students learn about rules in math by using a function machine.  Students are given a number, the end number, and have to figure out the rule is.  Sometimes they are given the number, and the rule, and they have to find the end number, etc.  This would be a fun game to use to have students practice that and then check their answers.
