Overview:

Discuss how you would communicate a letter of the alphabet to someone if all you could do is say a number between 0 and 26. (Students will usually suggest using a code of 1 for a, 2 for b, and so on).

Overview:

This is for students who are learning to identify numbers from 1 to 100. We have 15 different numbers, one on each card. You can’t see them but this time they are in order from the lowest number to the highest number. The numbers range from 1 to 100. Can you find number 52

Overview:

To make up a stop motion video or play that demonstrates that the giant is using a sequential search to eat the cows in order from heaviest to smallest and that the giant slayers who need to stop the giant from eating all the cows can easily find the giant before too many cows are eaten by using a binary search.

The Great Number Hunt (Sorted) (Ages 8-10)
Conditional Remix & Share Permitted
CC BY-SA
Rating
0.0 stars
Overview:

Guide students to discuss the algorithm or process that they would use to find a value in a sorted list and how that would be different in an unsorted list. Help them to recognise that the best way to search the sorted list is to do a binary search: it does matter what order they actually look at the books.

Rating
0.0 stars
Overview:

Guide students to discuss the algorithm or process that they would use to find a value in an unsorted list and how that would be harder than in a sorted list. Help them to recognise that the only way to search the unsorted list is to go through every item (whether they choose randomly or look at the first, then second, then third…) because they are still just checking and eliminating one at a time.

How binary digits work (Ages 5 to 7)

Rating
0.0 stars
Overview:

Did you know that right in the inside of any computer there are billions (that’s a really really big number) of little tiny things that can be turned on or off, like a light switch, and that when you have lots of these things together they can display a number or a letter or a movie or make up your favourite game on your device? So let’s look at how they work. Now we need to pretend that we are so incredibly small that we are now inside a computer and we are making the computer show a number.

How binary digits work (Ages 8-10)
Conditional Remix & Share Permitted
CC BY-SA
Rating
4.0 stars
Overview:

Explain to students that we're working with just two digits, so they are called binary digits. They are so common that we have a short name for them: write "binary digit" on a piece of paper, then rip off the "bi" at the start, and the "t" at the end, put it together and ask what the combined word ("bit") spells. This is the short name for a binary digit, so the 5 cards that they have are actually 5 bits.

Overview:

Place the 15 searching squares on a table. Explain that we have 15 different numbers, one on each card. Show that one side has an animal on it and the other a number. Under each of these cards is a number that you can’t see, and they aren’t in order. The numbers range from 1 to 15. Can you find the card with the number 12?

Show the students the Sorting Network again (if the network needs redrawing then students often enjoy doing this, and drawing it accurately from the diagram is a useful exercise). Tell them that they will be trying it with some variations this time.

Overview:

Play a note on a hidden instrument (e.g. a chime bar), and have a student try to find the note on the piano by guessing the note, and comparing it with the one being played. If the note on the piano is too high, explore the lower half, and vice versa. A kind of binary search can be used to narrow in on the note. You could also do a sequential search - keep playing notes until you hear one that is the same.

Rating
0.0 stars
Overview:

Adults use computers for important things like banking, writing school reports, and communicating with each other. If the information being stored got changed without anyone knowing, you'd get the wrong balance in your account (too much or too little), the wrong grade in your report, or the wrong message in an email. Or worst still the website you are wanting to go to for your learning or the DVD you want to play won’t work! This activity will look at how computers correct this automatically.

Reinforcing numeracy through a Sorting Network (Ages 11-14)
Conditional Remix & Share Permitted
CC BY-SA
Rating
0.0 stars
Overview:

Use the Sorting Network template to draw a 6 person Sorting Network on a paved surface outside using chalk (other alternatives include using masking/painters tape on a carpet or wooden floor, tape on a tarpaulin, or line marking paint on grass). Note that the Sorting Network needn't use different colours or line thicknesses, but if suitable chalk or tape is available, this can help students remember which way to go. It should be large enough that two students can comfortably stand in the rectangles; the more spread out it is, the more effective the exercise is. In a very confined situation, it could be done on a desk top using game counters instead of students moving around, but this is much less engaging.

Unit Plan: Error detection and correction
Conditional Remix & Share Permitted
CC BY-SA
Rating
0.0 stars
Overview:

The world is a complicated and imperfect place, and errors can occur when digital information is stored or transmitted. Data stored on digital devices can be changed if there is a tiny fault in the hardware (and these occur regularly); and data being transmitted over networks can be messed up if there's a problem with the connection (which is bound to happen at some stage). This unit and lessons explores how digital devices detect and correct errors in data, and why sometimes computers can detect errors, but don’t have enough information to correct them.

Rating

Overview:

Computers today use digits to represent information - that's why they're called digital systems. The simplest and most common way to represent digits is the binary number system, with just two digits (usually written as 0 and 1). It is called binary because there are only two different digits used, or two states.
