Welcome to the Double Dangerous Division Lesson and Quiz! Enter at your own risk! Read and study each slide carefully. Let's start with a review of the division algorithm. MizzterG An algorithm is a method or way of doing a math problem. It has steps that you follow. − × √ ÷ ↓ Subtract Check Bring Down Divide Multiply Place the names next to the symbols − × √ ÷ ↓ Subtract ? Check ? Bring Down ? Divide ? Multiply ? steps to doing a problem a way to avoid a problem it's a bizarre word in science a dancing ex-vice president What is an algorithm? 1 A division problem has three parts 2 3 divisor 2 3 divisor dividend 3 Study these parts divisor dividend quotient divisor ? Place the parts in the correct spots. dividend ? quotient ? Put the numbers in the correct places. period, command, imparative sentence 2 ? 30 ? 15 ? Nice! 2 Now, can you follow the algorithm you have been learning? 30 15 3 − ? − ? 123 12 ? 0 ? 4 ? 0 ? 3 ? 3 ? 1 ? If there are two numbers the same, use the shorter numbers early in the problem. first 3 3 next 3 − − 123 12 0 4 0 3 3 1 Hope you're getting it. Hope you're getting it. Check out the video on the next page. You will need sound. The last page will have a link to a site to practice with draggable division. Mr. Duey - Long Division Use the bar to control video, not the middle. If you want to practice draggable division on your own, check out the side below.
