Finding Missing Numbers and Sums

This video tutorial explores solving three addition problems with missing numbers. The instructor demonstrates how to find the missing number in equations by counting and grouping. The first problem involves finding the missing number in the equation blank + 3 = 11. The second problem is about solving 9 + blank = 14, and the third problem involves adding groups of seven and eight to find the total. The video emphasizes understanding addition through visual representation and counting.
