Sam did a great job showing us just one of his many strategies for solving 56+38 on an open number line. He started with the number 56 and did a jump of 20 which brought him to 76. Then, he did a jump of 4 to get to the friendly number 80. He added 10 more to get to 90 and then added the final 4 to get to his answer, 94. Great work, Sam! Ask your child how he/she solved this problem on an open number line.
