**Lesson Plan Adding and Subtracting Positive and Negative**

One advantage of the number line model is that it allows an unambiguous formulation of the basic concepts of \equal", \smaller" and \bigger" among fractions. Simple experimentations on the number line will expose students to the phenomenon... Here, a student places a beanbag on our integer number line. After we play several rounds of tug-of-war as a class, the students play the game in pairs using smaller game boards. To make positive and negative dice, I use a permanent marker on blank cubes.

**Open Number Lines Explained The Classroom Key**

Explain your thinking. Today’s Number is… Select a number for the day (e.g. 8) and write it on the board or chart paper. Ask students to suggest calculations for which the number is the answer. Write students' suggestions in 4 columns (addition examples, subtraction, multiplication and division). After 8 or 10 responses, focus in on particular columns or types of responses that you would...Number lines are extremely versatile for students to use when representing and explaining math problems. They add a visual element to the numbers and allow students to break apart and put numbers back together. We use number lines for addition and subtraction in second grade.

Invite a student to come draw on the number line to find the product. Hand out blank number number lines. Write a problem on the board (i.e. 2 x 7 ) and have students use their number lines and work with a partner to solve. how to get a tight tummy For example, it was easier for students to locate 7/8 on the number line in Fig. 7-2a than on the number line in Fig. 7-2b. FIGURE 7-2 Novillis-Larson's findings suggest children's apparent difficulty in perceiving the unit of reference: When a number line of length two units was involved, almost 25 percent of the children tested used the whole line segment as the unit..

## How To Explain A Number Line To Students

### Provide the students with an enlarged copy of the Equivalent Fractions on a Number Line Activity. Explain the activity to the class, then monitor and support the students as they complete the activity.

- As a number it is less than 1 and greater than 0, in fact "half" way between them, but it is quite common for students, the first time they are asked to place it on the number line, to locate it between 1 and 2, possibly because those are the two digits used in writing the symbol '1/2' or possibly because of the commonly-taught strategy of thinking of 1/2 as meaning "one out of two." Students
- To really use open number lines successfully, it helps if your students have these prerequisite skills: Smaller numbers to the left, bigger numbers to the right – If students have had exposure to standard number lines, then they will probably understand this.
- Materials: large model of a number line from 10 to +10 with the numerals for 0 to 10 written beneath their marks and the marks for the numbers 1 to 10, but not the numerals (See the number line below); strips of paper for students to make their own number lines
- I would say to him/her, think of a mirror placed at the number 0 (on the number line) facing towards your number. The negative of a number is like placing a mirror and result is the mirror image at the opposite side. If you want to know what is the negative of this new number again place the mirror at 0 facing towards this number. The mirror image is where you would find the resulting number
