Solving Near Doubles with Doubles Facts

The video tutorial explains the concept of doubles and near doubles in mathematics. It begins with a review of doubles facts, where two identical numbers are added together, such as 5+5 or 8+8. The tutorial then introduces near doubles, which involve adding numbers that are one unit apart, like 5+6 or 8+9. The instructor demonstrates how to use doubles facts to solve near doubles problems by identifying the smaller number and adding one more. Visual aids, such as colored cubes, are used to help students understand the concept. The video encourages students to practice and revisit the material as needed.
