Description: Are your students learning the area model for multiplication of whole numbers and making common errors? With these 80 error analysis task cards, students identify one error on each card and multiply whole numbers to find the correct product. From 2 digit by 1 digit multiplication problems to 3 digit by 2 digit multiplication problems---you have everything you need to scaffold and differentiate for your students! I've separated the Boom Card sets by the size of the multiplication required so that you can easily assign different sets to different students. Let's get those common errors corrected! 2 digit by 1 digit 3 digit by 1 digit 4 digit by 1 digit 2 digit by 2 digit 3 digit by 2 digit Common Errors Include: * Student’s partial product does not have enough zeros when multiplying multiples of 10 * Student records too many zeros when multiplying multiples of 10 * Student does not line up place values correctly when adding the partial products to find the solution * Student makes a multiplication fact error * Student does not yet understand what parts of the factors to multiply and therefore multiplies a factor within itself vs multiplying by the other factor parts * Student flips numbers (incorrectly transfers partial products) when recording them to add the partial products * Student does not expand numbers correctly when recording the hundreds/tens/ones to set up the problem
