Differentiation instruction is when you teach a concept using different approaches, ie, when you teach multiplication, you may teach it using the regular method or teaching the lattice method, etc.2nd Grade math

Mean, Mode, Median Computer Game This a fun way to learn the concepts of Mean, Mode, and Median. Students get to line up objects and then manually place the word "median" on the object that is in the middle To find the Mode, you put the objects in categories and then place the word "mode" on the category has the most. I let the students use a calculator to find the mean because it saves time in calculation.

Polygon Game ,This game is great for those who need extra practice with identifying different kinds of polygons.

Math Definition
Math definitions may need to be visual, so I created one for "sum".

I really enjoyed the video of "How to Teach Math as a Social Skill". I break students into group quite a bit and see the "me" syndrome. They lack the social skills needed to share in a group. Most of the students I would with want to either take control or be in the shadow. This video explains how it is necessary to set up the expectations before starting groups.

Dictionary for Kids This link is great for helping with all the amounts math vocabulary. The student can choose a math vocabulary word and then it shows an interactive activity to help reinforce the definition.

Finding the Mode, Median, Minimum, Maximum, and Range
Explain the definitions of Mode, Median, Minimum, Maximum using pictures. [|Maximum.doc]

[|Mode.doc]

[|Mean Mode Median.doc]

Materials: pictures of concepts of mode, median, minimum, and maximum deck of cards (take out the kings, queens, and jacks) index cards

Mode: Explain to the students, that to remember the definition of "mode," it is the number that you see the most. M__**o**__de/M__**o**__st both have "'__**O**__'s" in them. So when you look for the mode, you are looking for the number that you see the most. Put up visual to remind students of mode.

Median: Get a picture of a street with a median. Explain to the students that they are to see, that as the median divides the road in middle, the median is the middle number. Put up a visual to remind the students of median.

Maximum: Tell students that maximum is the largest. Think of things that are maximum. Put up a visual to remind the students of maximum.

Minimum: Tell students that minimum is the smallest or mini. Think of things that are minimum Put up a visual to remind the students minimum.

Range: Visual of the concept of range.

Put students in pairs. 1. Have the students write maximum, minimum, and range on index cards. 2. Pass out 5 playing cards to each group (I use an odd number, so that if makes it easier to find the median without having to divide. 3. Tell the students that the first step in finding the mode, mean, and median is to put the numbers in order. Instruct students to put cards in order from minimum to maximum. 4. Tell the students to put the maximum index card above the maximum number and the minimum index card over the maximum number. 5. Now ask them to find the mode by looking for the card that you find the most. 6. Now ask them to find the median by finding the number that is in the middle. 7. To find the range, instruct the students to move the minimum card behind the maximum card and subtract and that now that they have found the range.

Now let each student practice their new found knowledge by playing the.... Mean, Mode, Median Computer Game

Objective: Decimal Place Value __**Decimal Place Value Lesson 4.1 - 4.3**__

Materials: Number line .... I use the Lesson 4-1 p. 78 and write in the answers Index cards... I use the Lesson 4-1 p. 78 for numbers

1. Prepare index cards with various decimals (about 5-7 per group of students). ... I use the Lesson 4-1 p. 78 for numbers 2. Using a number line, order the decimals.

Decimal Activities I added this link because it give concrete worksheets for those struggling math students.

I added this activity for students who needed extra practice with Decimal Place Value.

Use decimal cards made for the previous activity to practice order of decimals.
 * WARM UP:** 5-7 minutes

__Ordering Decimals__
Ordering decimals can be tricky. This is because often we look at 0.42 and 0.402 and say that 0.402 must be bigger because there are more digits. If you follow the following method you will see which decimals are bigger.
 * Set up a table with the decimal place in the same place for each number.
 * Put in each number.
 * Fill in the empty squares with zeros.
 * Compare using the first column, and pick out the highest in order.
 * If the digits are equal move to the next column until one number wins.

Example
Order the following decimals: 0.402, 0.42, 0.375, 1.2, 0.85 In a table they will look like this:


 * Units || Decimal Point || Tenths || Hundredths || Thousandths ||
 * ~ 0 ||~ · ||~ 4 ||~ 0 ||~ 2 ||
 * ~ 0 ||~ · ||~ 4 ||~ 2 ||~ 0 ||
 * ~ 0 ||~ · ||~ 3 ||~ 7 ||~ 5 ||
 * ~ 1 ||~ · ||~ 2 ||~ 0 ||~ 0 ||
 * ~ 0 ||~ · ||~ 8 ||~ 5 ||~ 0 ||


 * Compare the Units. || [[image:http://www.mathsisfun.com/images/arrow.gif width="30" height="30"]] || There is a 1, all the rest are 0, so 1.2 must be the highest. (Write it down in your answer and cross it off the table). ||
 * Compare the Tenths. || [[image:http://www.mathsisfun.com/images/arrow.gif width="30" height="30"]] || The 8 is highest, so 0.85 is next in value. ||
 * There are two numbers with the same "Tenths" value of 4, so move down to the "Hundredths" for the tie breaker || [[image:http://www.mathsisfun.com/images/arrow.gif width="30" height="30"]] || One number has a 2 in the hundredths, and the other has a 0, so the 2 wins. So 0.42 is bigger than 0.402 ||
 * Go back to comparing the Tenths || [[image:http://www.mathsisfun.com/images/arrow.gif width="30" height="30"]] || 0.375 must be next followed by 0.2 ||

The decimals must be in the order, highest to lowest: 1.2, 0.85, 0.42, 0.402, 0.375 Done! For those who need hands-on, have the students put the decimals on index cards and order them using the index cards. Now that everyone knows the ordering of decimals, it's time to practice on the computer. Ordering Decimals Computer Activitie **__ Review of Basic Decimal Concepts Lesson 4.2 __**  For this activity, I used the Teaching Aid Master on p. 426 and made them into overhead transparencies for each student. The students can then use a visa-a-vis pen to color in the decimal amount. Place Value of Decimals __** Decimal Addition and Subtraction Lesson 4-5 **__  For those students who don't understand the whole decimal concept, Key Currriculum sells these wonderful workbooks that break down the concept into micro steps. I use them in my classroom. Decimals Workbooks
