sequences

Sequences occur all our lives. For example when we count, 1..2...3... and so on. when we multiply by a given number, 1*2, 1*3 and so on. But a known mathematical example of sequences are Fibonacci's. Arithmetical. Pascal's triangle use sequences through out the entire triangle. It is important for young elementary children to learn patterns and sequences. With out them the will struggle in math.

Children struggle with math almost everyday. The website: www.JustMathTutoring.com can help with many different areas of struggles like graphing, calculating expressions and other things. This is the best Website i found was very helpful. The website had activities to help with pascal's triangle, fractions, graphs and regular number sequences.

Here is a video on Pascal's triangle.
Here is a video on Fibonacci sequence.
Here is a video on Number sequences.

Logic and Everday use

Logical reasoning is very useful when the brain can do it. logical reasoning is also called deductive reasoning. We use deductive reasoning when trying figure out puzzles or mind games. It is important to keep up on use your deductive reasoning in order to stimulate your mind. Doing sudoku puzzles are an excellent way to do this, or simply playing games like color by numbers or any simple math activity.

When figuring out what logical reasoning was, i stumbled across a website for second graders. I entered the website and it had six different areas of math. I found particular section 6, which was Mathematical reasoning. I clicked on to the selection and it came up with different activities for 2ND grade children to access, the sections i found fun were the brain teasers. Click here to access website.

One other website i ran into for logical reasoning for elder kids was here.

Functions

Everyday functions are apart of our daily lives. Whether we are using them for math, for recording grades. or we are just drawing simple shapes.

Every functions has coordinate pairs. These pairs are used to place different points on to coordinate plane. In which the pairs consist of x and y coordinates. The x coordinate fluctuate from left to right. the y coordinates fluctuate from bottom to top. Each pair label (x,y) and used to place the the corresponding coordinates with each labeled number. For example the pair (4,5) would be placed on the number 4, x line and placed where the y coordinate 5 line intersects.

Here is a video for graphing functions.

For beginning to learn how to graph functions use this video.

Venn Diagrams

Venn diagrams are a good way for people to compare and contrast different things on a visual basis. they can see the differences between two things. We'll create an example. We will call one A and the other B. Lets say A represents what you like. And Bis what your best Friend likes. You both will have some differences and some similarities. The similarities will be called C.
Using circles draw two that slightly overlap. The overlap will represent Section C. the Others will be A and B. Section C is also called the intersection. Here is an link to show you what i am talking about.


Here is a video i found on You tube where children at an elementary school create a human Venn diagram.

This video gives more information on different types of diagrams Like conditional probability.

flashback

Just as i thought math was only going to get boring. That we were just going to sit and listen to teacher talk for two or three hours, i went to math and our teacher had us learning with color tiles like we used in elementary. I am a visual learner so being able to learn with the color tiles on how to find ways to make perimeters of 20 and twelve in all kinds of different ways was fun. Being able to play with math made me feel like i could be able to do almost anything with it. Using the color tiles for making models of shapes with different perimeters was a good way of having a strategy for problem solving.

Color tiles is a fun way to use colors and shapes for young children to learn. here is a video i found on YouTube with making shapes with color tiles. This link will take you to a website with activities for hands on math for younger kids using spinners, colored tiles, color shapes and more.
