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)

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)

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.
