296 ÷ 4 = _____
We need to break down 296 into parts that are easily divisible by 4. STEP 1: Look at your largest place value 296 ÷ 4 = _____ I look at my first digit. Can I make a group of 4 out of 2? No. So then I “add” on my second digit. STEP 2: Look at the first and second largest place values together 296 ÷ 4 = _____ I look at my first and second digit. Can I make a group of 4 out of 29? Yes! STEP 3: Find the closest multiple without going over. 296 ÷ 4 = _____ So now we look for a multiple of 4 that’s close to 29 without going over. Step counting from 4: 4, 8, 12, 16, 20, 24, 28. 28 is the closest multiple; however the value of 28 is 280. So 280 is our first part of 296 that we’ll use. STEP 4: Divide 296 ÷ 4 = _____ 280 ÷ 4 = 70 STEP 5: Subtract 296 ÷ 4 = _____ 280 ÷ 4 = 70 Now that we know 280 is easily divisible by 4, we need to find out what’s leftover to divide, so we subtract 280 from 296. 2 9 6 - 2 8 0 1 6 Our last part of 296 to divide is 16. STEP 6: Divide again. 296 ÷ 4 = _____ 280 ÷ 4 = 70 16 ÷ 4 = 4 STEP 7: Add the quotients. 296 ÷ 4 = _____ 280 ÷ 4 = 70 16 ÷ 4 = 4 Now we’re going to add 70 + 4 = 74 So 296 ÷ 4 = 74 Practice Game: Baseball (2 Players)

Prime numbers are numbers that can only be divided by itself or 1. For instance we know that 2 is a prime number because only 1 and 2 multiplied make 2. However if a number can be divided by more than just itself and 1, it is known as a composite number. An example of this would be 6 since its factors are 1, 2, 3 and 6.

In other words, when given a number like 24 we are looking for what numbers multiplied together equal 24. In the case of 24, its factors would be 1, 2, 3, 4, 6, 8, 12, and 24.

Multiples Game: Number Ninja Multiples Game: Multiple Frenzy Practice Problems The multiples of any given number are infinite however the factors of a number are limited. Also factors, are smaller than the number given whereas multiples will be larger. Practice Problems Rounding Games (Bike Racing) Rounding Games (Brain Racer) Rounding Games (Soccer Math) Rounding Games (Fly Delivery) When rounding numbers to the nearest ten, hundred, thousand, etc. you look to the digit to the right of the digit you're rounding to see if your rounded digit stays the same or is rounded up. If the digit to the right is 5 or more, the you round up. If it is less than 5, then it's rounded down. For instance if I'm rounding 5,369 to the nearest ten, I would look at the ones place (9) to see if my tens place (6) is rounded up to 7 or stays at 6. Since my ones place is greater than 5, then my tens place is rounded up to 7. Also, all digits following the rounded digit becomes 0.
