METRIC LENGTH
Length is a measurement that tells how long or wide something is.
In the olden days people measure length of objects by using various parts of the body such as arm, foot, palms etc. But all these does not give accurate measurements.
Today people use instruments like ruler, tape rule, meter tape to accurately measure the length of objects. The standard unit of length measurements s metre (m)

CONVERSION OF METRIC LENGTH
10 millimetres (mm) = 1 centimeter (cm)
10 centimeters = 1 decimetre (dm)
10dm = 1 meter (m)
1000mm = 1m
100cm = 1m
1000m = 1 kilometer (km)

Examples

Solutions
a. The length of line a is 6cm
b. The length of line b is 2.5cm

Pupils should be Able to ;
Define length, find the various units of measuring length and also use a ruler to measure length of certain objects.

Begin the lesson by  showing pupils a video about how length is being measured.

STARTER
The pupils are given a Worksheet which contains different lines, object and animals. Then with the aid of ruler they are to measure their lengths.

Addition of metric length is similar to basic addition arithmetic. But note:
10mm = 1cm, 100cm = 1m, 1000m = 1km
EXAMPLES
1. Add 10cm 5mm to 15cm 7mm and  12cm 5mm

Solution

2. 5m 15cm 7mm + 4m 48cm 9mm + 6m 65cm 8mm
Solution

PLENARY
Pupils should be able to add various units of lengths together.

STARTER
Start the lesson by asking them questions on units of length and perform basic addition operation.

SUBTRACTION OF METRIC LENGTH
Subtraction of metric length is similar to basic subtraction operation. But note:
10mm = 1cm, 100cm = 1m, 1000m = 1km
EXAMPLES
1. Subtract 5cm 9mm from 9cm 6mm
Solution

PLENARY
Pupils should be able  to subtract various units of lengths.

STARTER
Begin the lesson by asking them questions on simple subtractions problems.

### DO YOU SEE THESE STRANGE LINES ON YOUR NAILS? DON'T JOKE WITH IT, THIS IS WHAT IT SAYS OF YOUR HEALTH

As I’ve gotten older, those vertical ridges on my nails seem to be getting more and more prominent. That’s when I decided to do some research to see if those ridges meant anything about my health, and if there was anything I could do to get rid of them. What They Mean About Your Health After a lot of research, I did find that there is a small, rare possibility that those ridges can mean an underlying medical condition or possibly even nail trauma. But for most of us, it’s completely normal as we age to see them getting more noticeable, especially if you have dry skin or skin conditions such as eczema. I’m 36, and they’ve only recently started bothering me, but I’m relieved to find that they are most likely harmless. I’m just getting old. But Why Are They There? They’re basically like wrinkles of the nails! As we age, the nail matrix gradually starts to lose it’s effectiveness in some areas, causing your nails to grow out uneven, resulting in what we see as lines or ridges that run from

### DISCOUNT AND COMMISSION MATHEMATICS LESSON PLAN AND LESSON NOTE FOR PRIMARY AND SECONDARY SCHOOLS

Monday   Meaning of Discount  Finding cost and cash price on discounted goods Resources  Inside out  Learn   mathematics Book 6, page  125  items like; currency note Milo, biscuits, books, pencils, school bag   Meaning of Discount Discount is a reduction in the price of an article. It is often a certain percentage of the actual price of the article. Examples 1. A table clock cost \$200, and a 10% discount is given for paying cash. What is the cash price? Solution The discount = 10% of \$200 =   10     x 200= 20 100 So Cash price = original price – discount                                                             Amount   =    \$200 –  \$20 = \$180  2. The selling price of a shirt is \$900. The trader gives 5% discount for cash. How much is the buyer paying. Solution The discount = 5% of \$900 = \$45 So Cash price = original price – discount amount                         = \$900 – \$45 = \$855 Begin the lesson by showing them an image of a market where buying and selling is taking place, then

### METRIC WEIGHT LESSON PLAN AND LESSON NOTE FOR PRIMARY, SECONDARY AND HIGH SCHOOLS

SUBJECT: MATHEMATICS                W.A.L.A:  METRIC WEIGHT                                                                 Day s W.A..L.T:  Content  Plenary  Starter  Task  Homework  Monday   To measure weight of various objects. Convert units of weights Resources  Inside out  Learn   mathematics Book 6, page  42 Weighing balance, scale balance, stones, and bottles. INTRODUCTION TO METRIC WEIGHT The heaviness of an object tells us what weight is. There are various objects for measuring weight such as the scale balance, the weighing and the spring balance. The basic unit of measuring weight is gram (g). The weight of heavy objects like bags of cement are measured in kilograms while light objects like pen, pencil are weighed in grams. CONVERSION OF METRIC METRIC WEIGHT 10 milligrams (mg) = 1 centimeter (cg)  10 centigrams = 1 decigrams (dg)  10dg = 1 gram (g)  100cg = 1g 1000g = 1 kilogram (g) 1000kg = 1 ton (t)   Pupils should be Able to ; Define weight, find the various units of measu
