iLiveMath Speed uses race cars, sail boats, jets, the Space Shuttle, and more to teach Distance = Rate x Time, ratios, km/hour, mph, knots, and speed of sound terms such as Mach, supersonic, and hypersonic in a word problem format! I really like this app because it introduces Physics as a multiplication word problem appropriate for older elementary school students.
I don’t know about you, but I really struggled through Pre-Med college physics and had to get friends to help explain basic concepts to me (i.e. see how we are walking at the same pace? That’s speed. Speed = distance X time [miles per hour or mph or km per hour]. Now we are walking faster. Acceleration is the increase in speed. The formula is acceleration = force / mass. Force = mass X gravity.) Yikes! It gets complicated quickly that it is nice to introduce these concepts in a fun way such that it becomes intuitive rather than a memorization of formulas. This app doesn’t actually cover acceleration but by teaching Distance = Rate x Time, it’s an appropriate and intuitive introduction to physics for an elementary school student.
The format of iLiveMath Speed is similar to iLiveMath Trains so click here to read that review which goes over some nice features in both apps such as the roll-y answer bar and the number sentence for correct answers.
Here are the levels for iLiveMath Speed with a sample problem from the app.
Level 1: Addition and Subtraction
A lead pack of 13 Formula One cars drafted in a line and as they rounded a turn, 2 zoomed ahead. How many are left behind?
Level 2: Addition, Subtraction, and Multiplication (speed, rate, distance and time)
If sailboats raced at an average speed of 16 knots, how many nautical miles are traveled in 2 hours? (1 knot = 1 nautical mile/hr).
Level 3: Advanced Addition, Subtraction and Multiplication (with speed, rate, distance and time)
If a Maglev train journeyed at an average speed to 223 mph, how many miles are traveled in 7 hours? (Distance = Rate x Time)
Again, like iLiveMath Trains, there are appealing photos of things that go fast as well as fun sound effects. Here are some screen shots:
This app is appealing to boys but I would try girls out on it as well! The app is $3.99 and can be purchased at iTunes. You can click on the little icon above to check out at iTunes.
