100 Hunt

(Ages 5 and up)

Find a number on a number square or work out 9, 10, 11 and 20 more/less.

Try the Find Any Number level first. Look at the target number and find it as quickly as you can.

There's a timer to show you how many seconds you took, (after 99 seconds it says 'Ex').

Once you've mastered the patterns of the number square try adding 10 or 20.
After that try adding/subtracting 9 or 11.

The two player game is great for a challenge with a friend.
If that's too easy why not be brave and try the random level!

This game gives you a number square beyond 100 as children find counting past 100 tricky.

Some schools prefer a square that starts at zero, whilst others prefer to start at one. You can switch between the two at any time.

This isn't your dad's punching bag as it will throw punches if you don't answer the number comparison statement correctly or you take too long.

Compare the number on the left to the number on the right and then press the correct button ("<","=",">"). You'll lose a glove (life) if the countdown timer reaches zero before you answer or you answer incorrectly. As you complete a level the numbers get larger and the time gets shorter! See how far you can go.

Drive your tank safely through the minefield by comparing numbers. Mines with correct answers are safe to go over while mines with the wrong answer will disable your tank. Try and get to the end of each level without tripping a mine.

Use the comparison problem in the hint found before the mines to figure out which mine is safe. The mine with the correct answer is a dud and is safe to drive over. Click the tank to stop and start it and tap to the left or right of the tank to shift it over in that direction.

Half-court Rounding is a game in which students try to score as many points as possible by rounding numbers to the nearest ten, hundred, or tenth. This is a perfect game across grade-levels, because students can choose to shoot free-throws (1 point - round to the nearest ten) jump shots (2 points - round to the nearest hundred) and three-pointers (round to the nearest tenth). Users can try any kind of shot within the game and have 90 seconds to score as many as points as possible and beat their opponent. If they answer incorrectly, the student misses the shot. Students can also choose a two-player game where they can play a friend or classmate.

Time Machine

Professor Mathstein has been busy trying out his rounding numbers time machine. While the machine works and runs smoothly, Professor Mathstein requires assistance in getting it started. He needs someone to activate the machine as he waits inside the capsule.

To activate the time machine and get the professor's journey started, round the number provided on the top of the capsule up to the nearest tens. There are two options available on the control panel, and each of them is a number relatively close to the number shown. However, only one of them will work on the time machine.

Pick your answer by swiping the bar towards the number that you require. Once you have done that, the time machine will start up. If you have succeeded in rounding numbers to the right answer, Professor Mathstein will disappear right before your eyes. Which means he is probably hanging out with The Beatles as we speak! However, if you get the answer wrong, the time machine will sputter and create a small explosion, resulting in a very angry and blackened professor. Time travel is tricky, so just try again and hope the professor does not stay angry for long!

Time Machine is a game that expands the understanding of place value. This knowledge progression is applied to the training of learning to round things up to the nearest ten. By practicing to round 3-digit numbers up to the nearest ten, you are setting a very solid foundation for future mathematical concepts and observations in summarising whole numbers to closest estimations.

Note for parents and teachers: Though this game helps children practice estimation, it does not teach strategies for estimation. Before having your child or student play this game, you should discuss estimation strategies with them. Read the section titled "Estimation and Children" for an estimation strategy children can use.

Guess It! is a game which will help children develop their ability to make approximations and estimates. In this game, Professor Puzzler will show the child a group of objects scattered randomly on the screen. The child will have a few seconds to look at the objects; there will not be enough time for the child to actually count the objects.

After a few seconds, Professor Puzzler will remove the objects, and then give the child a multiple choice answer selection. The child must click on the answer which best approximates what the child has seen on the screen.

For some questions, Professor Puzzler will scatter two or more types of objects on the screen (for example: red dots and blue dots) and ask the child to tell whether there is more of one kind or the other.

The child will also encounter objects of different sizes, which will add a bit of extra challenge to the question, since objects which are larger take up more area on the screen, even if there aren't as many of them.

For some children, estimation is a difficult concept. Children want to be right, and if there are 18 objects, saying there's "about 20" is not good enough.

Of course, in mathematics we encourage children to calculate the correct answer, but being able to estimate is a valuable skill. First, because it shows that you have a good sense of numbers and how big they are. Secondly, because children who have that number sense will be able to use that skill to determine whether their answers to math questions are reasonable.

If you want to give your child or student an estimation strategy, here is one exercise you can do with the child: Take a sheet of paper and draw about thirty randomly placed dots on it. Now give a pencil to your child and say: "Draw a circle around ten dots." After your child has counted ten and circled them, say "Now look at how many dots that is. Do you think you could draw a circle around about ten dots, without actually counting them?" Your child may try counting--this is normal! If they try to count, just say, "Oh, I see you're counting. You know about how many ten is--you don't have to be exact, so next time don't count, just make a guess as close as you can without counting." After doing this a few times, your goal is for your child to get better at dividing objects into groups of ten. Once they can mentally divide objects into groups, show them that if there are three groups, that means there about thirty objects in all.
