Definition: (applied mathematics) A data chart (graphical representation of data) intended to illustrate the relationship between a set (or sets) of numbers (quantities, measurements or indicative numbers) and a reference set, whose elements are indexed to those of the former set(s) and may or may not be numbers.

Alright class, settle down, let's take a peek, At “graphs,” a concept we need to speak! That dictionary definition’s quite grand, Let’s break it down with a helping hand. Basically, a graph is a visual treat, Showing how numbers relate, oh so sweet! Think of it like this, a colorful display, Of data arranged in a special way. “Data chart” – that's part of the plea, Representing quantities for you and me. We’ve got sets of numbers, don't you see? And a reference set, for clarity! Indexed to those numbers, neat and precise, Showing connections with wonderful price... …of understanding! It helps us find, The patterns hidden in our mind. So graphs aren't just lines, or circles bright, They’re tools for seeing, shining light! They show trends and changes, clear and bold, Stories in numbers, to be told! Do you have any questions now, my dear friends? Let's discuss it further, until the very end!

Definition: A passage in text that is about a different subject from the preceding text, marked by commencing on a new line, the first line sometimes being indented.

Alright class, settle down and let’s take a look! Today we’re tackling “paragraphs,” a word you'll hear quite often. The dictionary gave us a good start, didn’t it? Let’s break it down nice and slow. Think of it like this: imagine you’re building with LEGO bricks. You wouldn't just pile them all together randomly, would you? No! You build sections , little groups that focus on one thing at a time. A paragraph is much the same for writing. It's a section of text – like a small group of ideas. It’s about a different subject than what came before. Just like you wouldn’t talk about building a castle and then immediately start talking about baking a cake! They are separate thoughts, clearly shown. The dictionary also tells us it starts on a new line – that's right! It needs its own space to breathe. And sometimes, the first line gets a little indent, like pulling it slightly back from the edge of the page - that’s a visual cue to show it’s a brand new section. So, in short: A paragraph is a chunk of writing about one main idea, starting on its own line and often with an indent. Does that make sense? Do you have any questions about how paragraphs help us organize our thoughts and make our writing clearer? Don’t be shy – let's discuss!

Definition: A picture created by projecting an image onto a photosensitive surface such as a chemically treated plate or film, CCD receptor, etc.

Alright class, settle down now, let’s take a look and see, At the word “photographs,” it’s quite simple, you agree? The dictionary gives us a clue, a helpful little plea, "A picture created… for all to see!" Let's break it down in pieces, nice and slow, So every single student truly knows. “Photo” comes from “light,” you understand? – Like sunshine bright across the land! And "graphs" means pictures, a visual display, Of something captured there and then today. It’s about light hitting a surface, that's the key, A plate or film, or even CCD, you see! These things are sensitive to light, it’s true, They change when light shines through and through. So a photograph is made with light’s embrace, Creating an image in its special space. Does that make sense? Any questions for me? Let's discuss!
