There are a number of other branches of math today, but in the future, there may be even more.
Euclid was a Greek mathematician.
You may have to take trigonometry in high school.
Isaac Newton is also a famous scientist.
Some people are great mathematicians, but for really complicated problems, most people will use a calculator.
The abacus was developed thousands of years ago. It is a simple rectangular frame with a set of rods in the middle. The rods have beads or balls that slide up and down. Someone that knows how to use an abacus can easily add very large numbers quickly. The abacus was good for adding numbers, but some math problems can be a lot more complicated than addition.
The slide rule came along in the 1600s. Slide rules can be straight or circular. A skilled user can multiply, divide, and even do trigonometry by sliding parts of a slide rule in different directions and reading the numbers that are shown on an indicator, or cursor. Slide rules were popular well into the 20 th century.
The first real portable calculator was made in the 1940s, but it had a crank instead of keys! Eventually, battery operated pocket calculators became popular.
There was even a trend of people wearing tiny calculator watches. Now every smartphone is a calculator, and they can do a lot more than an abacus or a slide rule.
People have been using devices to help them with math for thousands of years.
You would probably have no idea how to use an abacus or a slide rule, or even the first crank-operated portable calculator. That is not a problem because modern calculators can do much harder math than those first math machines, but they

The slide rule was another simple calculating device.
The abacus was the first mechanical device designed to solve math problems.
Modern calculators are more powerful than early math machines.
Mathematicians don’t always use calculators.

The slide rule was another simple calculating device.
Note: Student responses may vary, but the next sentence should introduce the slide rule.
The first portable calculator was not available until the 1960s, and it was nothing like the tiny pocket calculators you might find in a classroom, or the virtual calculator on your phone. Modern calculators are more powerful than the first math machines, and they make solving math problems much easier.
Note: Student responses may vary, but the final sentences of the introduction should introduce portable calculators and then provide a closing statement, wrapping up the whole introduction.

Math is a large field that covers several different branches. The first type of math children learn is arithmetic. Geometry is another branch of math that children start to learn at an early age. Trigonometry is more complicated than arithmetic and geometry. There are only a few of the various branches of math that exist now, but mathematicians also continue to develop new forms of math.
Note: Student responses may vary, but the first sentence should introduce arithmetic. The next sentence should introduce geometry, and the next sentence should introduce trigonometry. The final sentence should be a concluding statement that wraps up the introduction.
