Are students learning the area model for multiplication of whole numbers and making common errors? With these error analysis task cards, students identify one error on each card and find the correct product. I've provided explanations of the common errors I've observed and incorporated into the task cards.
This set of 80 task cards includes 16 cards for each of the following levels of multiplication:
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
I've included a variety of cards on these levels to allow you to differentiate your error analysis practice. These are perfect for classrooms with students on different levels.
* All answer keys and a student recording sheet are included!
Use these cards for whole group error analysis and independent practice to help students learn to look at their own work more objectively and to help them correct any common errors they have internalized.
4.NBT.5: Multiply a whole number of up to four digits by a 1-digit whole number, and multiply two 2-digit numbers, using strategies based on place value, the properties of operations, illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
