Why did I write Two Plus Two Is Not Five and what makes it different from other math workbooks?
This 256-page reproducible workbook is for students of any age who need to learn to memorize addition and subtraction facts. You may find that some children begin to struggle in math once reaching the 3rd or 4th grade, and most likely it is because they missed memorizing answers to the some of the math facts. For this reason, as an educator, I knew I had to find a way to help my students become proficient with math facts.
Math facts are “keys” to being able to do more complex math, just as letter sounds or phonemes are important to learning to read fluently.
It is so much easier to learn and practice math facts when presented with a visual or number sense strategy than to have to count out the answers, use a chart or number line to complete assignments on math facts. Yes, math facts should be introduced with counters to make sure the students understand what the math fact means, but then they need a way to have recall without having to count out answers.
This workbook can be used for beginning students or with older students who have some mastery of the addition and subtraction facts. The record-keeping pages in the book allow you to see where to begin. Please view sample pages and try them out!
