This is a great lesson activity to review Chinese numbers. After reviewing numbers in slide one, teachers can go through slide 3 to slide 11 by having students guess the number according to each image. Slide three (answer is 4 since we have four seasons in a year) Slide four (1 since gold medal represents number one); Slide five (8 since it is octopus). This way teaches students to think instead of counting the number of objects in each image. in Slide 12 to 19, students need to answer if the numbers match or not.
