My lesson was designed to fulfill the fourth grade Common Core Standard that students will “multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models,” (Council of Chief State School Officers and National Governors Association, 2010). My students have been learning and practicing solving these equations using the grid method, which breaks the numbers into place value; so that students can easily multiply the numbers in an organized manner. The students for this lesson are children who receive special education services for mathematic calculation skills and mathematic problem solving skills. These students are participating in a summer tutoring programs to keep mathematic skills current over the summer. The task for students is to determine the error that occurred using the grid method for multiplication in a work sample.
This learning experience was effective for my students because they were able to show an understanding of the mathematical goal. The main learning goal for the lesson was for students to show an understanding of two-digit multiplication by discovering an error in grid process. All three students were able to locate the error. Each student attacked the problem in a different manner and used different accommodations based on their ability level; nevertheless, they solved the problem. Communicating the error
