Let's step into an imaginary land filled with fun math activities! On page 1 of the workbook, how much money is in each safe? Count and place the decimal in the correct position. Don't forget to zap through the maze to catch Carl! Next, on page 2, these pirates loved boasting. How much booty did they actually get? Determine who bragged the most and who the least. Before leaving this imaginary land, help Gary the Magician on stage by solving the puzzles. Gary's assistant Rupert needs a vacation. Can you help, too?
On page 1, the decimals need to be included. Kids learn that putting in a decimal will change the value of the number. Imagine you have a number like 50. If you move the decimal point one place to the left, you change it to 5.0. This makes the number ten times smaller!
On page 2, kids learn that multiplying by 10 or 100 changes its place value. When you multiply a number by 10, each digit moves one place to the left, making the number ten times bigger. For example, if you have the number 5 and multiply it by 10, you get 50. If you multiply a number by 100, each digit moves two places to the left, making the number one hundred times bigger.
On page 3, kids will review what they've learned. Each place tells us how big or small the number is. For example, in 123.45, the '1' is in the hundreds place, the '2' in the tens place, the '3' in the ones place, the '4' in the tenths place, and the '5' in the hundredths place.
