Kavi Looks Back at Term 1

At the end of the term, Kavi sat down with a mug of acorn tea. "Look how much we learned!" Kavi hooted. "We taught a program to choose with IF–THEN — that's selection. We kept a score in a box that changes — that's a variable. We saw how a computer takes information in, works on it, and gives it back out — input, process, output — and we met the CPU, the memory and the storage inside. And we put facts in a spreadsheet and picked the right chart to answer a question — that's data." Kavi smiled. "Let's look back and make sure we remember it all."

What your child will learn

1Everything we learned in Term 1This term had four big ideas. Tap each one to remember its job — then you will be ready for the review questions.

2Read the rule, pick the roadSelection chooses between two roads. Read the IF–THEN line, check if the condition is true, then say which road the program takes. Reveal to check.

3Does it go IN, or come OUT?A computer takes information IN and gives a result OUT. Keyboards, microphones and cameras put things IN. Screens, speakers and printers give things OUT. Tap the right box for each one.

4A fixed number, or a box that changes?Some numbers never change — the number 7 is always 7. But a score goes up and down. A variable is a named box whose value you can change again and again, so it is perfect for a value that keeps changing.

A peek inside

Rule: IF the score is above 10 THEN show a star, ELSE keep playing. The score is 7. What does the program do?

7 is not above 10, so the condition is FALSE → take the ELSE road

Try this at home: When a program picks between two roads with IF–THEN, that is called ____.
