Your students will LOVE to practice their Addition and Subtraction facts with the Robot. Students input the numbers and they choose the answer to the problem that the robot shows as output. The level of difficulty increases a little as the lesson continues because students go from choosing only one addend or number in the equation along with the answer that makes it a true statement to having to choose all 3 numbers to make a correct math statement. The students will need to use critical thinking skills to find a solution that works. Each problem only has one solution that will work. All slides are self correcting so the lesson can easily be used in an independent station; as a teacher directed mini lesson; or in a small group. This makes a great way to practice math facts with students when you have a few minutes before lunch or recess!! Can be used over and over. Great for grades 1-6 because it can be used as an introduction, practice, review and remediation... or just as a fun way to brush up your facts. This is really a fun activity to use for Valentines Day because of the heart theme, but it is appropriate year round. MUST have SMART Notebook software to download and use this lesson.
