Familiarity with fractions | Presentation for a lesson in mathematics (grade 5):
Slide 1
The concept of a fraction. Common fraction 1
Slide 2
A long time ago … It’s good when there is a whole apple on the table, and you can eat it alone. But sometimes you have to divide the apple into parts, i.e. crush to share with anyone. This is how FRACTIONS are obtained. Remember how it was in the children’s cartoon: “We shared an orange, There are many of us, but he is one … Give your life example of dividing one whole object into parts. Interestingly, did they know about fractions in ancient times? 2
Slide 3
In ancient times, integers and fractional numbers were treated differently: preferences were on the side of integers. “If you want to divide the unit, mathematicians will ridicule you and will not allow you to do it,” wrote the founder of the Athenian Academy, Plato.
But not all ancient Greek mathematicians agreed with Plato. Fractions were freely handled by Archimedes and Heron of Alexandria. 3
Slide 4
Even Pythagoras, who was kind to natural numbers, when creating the theory of the musical scale, connected the main musical intervals with fractions. 4
Slide 5
I want to know and be able to do everything — How can I write down half of it in numbers? Take a strip of paper. Divide it into 2 equal parts by folding the strip in half. Draw a line along the fold line. How many equal parts was the strip divided into? (In 2 parts) Let’s write the number 2 under the line like this: . The line is called fractional, and the number written under the line is called the denominator. Color one part red. How many parts are colored red? (Part 1) Let’s write the number 1 above the fractional bar like this: The number written above the bar is called the numerator. CONCLUSION: (one second) part of the strip is painted in red (in practice it means half of some value) 5
Slide 6
Ordinary fractions Everyone can see a fractional line from a mile away.
Above the line — the numerator, you know, Below the line — the denominator. Such a fraction, of course, must be called ordinary. Name the numerator and denominator of each fraction
Fractions in Ancient Russia ½ — «half», » half» ⅓ — «third» ¼ — «quarter» ⅙ — «half third» ⅛ — «half a quarter» ⅟ 12 — «half a third» In ancient Russia, fractions were called fractions or broken numbers. 9
Slide 10
REMEMBER! … are called rational numbers, ordinary fractions or, in short, fractions numerator fractional bar denominator (by how much divided) The denominator is not equal to zero! 14
Slide 11
When reading fractions, you need to remember: the numerator of a fraction is a quantitative feminine number (one, two, eight, etc.), and the denominator is an ordinal number (seventh, hundredth, two hundred and thirty, etc. ) For example: — one fifth; — two sixths; — eighty three hundred fifty second 15
Slide 12
The denominator shows how many shares are divided, and the numerator shows how many such shares are taken.
