Multiplication Algorithm: multiplying a two-digit number by a one-digit number

Created by

This PowerPoint presentation includes 10 slides that will help make learning about the multiplication algorithm easy and fun. I have broken each step down and included animation and color to make this sometimes tricky concept easy to understand. The final allows for independent student practice. This can either be done whole class or you can print it out for individualized needs. I hope this tool helps you!

This worksheet helps students explore different approaches to subtracting numbers with multiple place values (regrouping). It is Jack Sparrow themed and I always make my kids speak pirate during the lesson. At the bottom of the sections are hand signals to give you ideas about motions that you can use to accompany chants. Enjoy! This item has been reloaded in both PDF and Word format.

One way to add and subtract mentally is to understand the role place value plays. Too often, students are taught only one way to add and subtract by using regrouping as the algorithm. While this knowledge is important, having the number sense to add and subtract two and three digit numbers (or more!) helps the student to visualize what he or she is doing when problem solving mathematically. This set of worksheets gives a brief explanation and example of the thought process behind adding and su

Hey Mr Daniels

Your students will think it’s a game; a chance to “take on the teacher.” You know that by playing this game, your students will review and practice borrowing and carrying skills and practice the steps of the addition and subtraction algorithms. “Build a House”™ is a fun, fast-paced math game with the same rules as “Hangman,” but instead of your students calling out letters, they call out numbers. Instead of hanging a poor, unfortunate stickperson, incorrect guesses will build you a house. Pick
