This Application Problem is a part of the Lesson 13, Unit 5, Grade K. Vincent's father made 15 tacos for the family. Show the 15 tacos as 10 tacos and 5 tacos. Draw a number bond to match. This Application Problem is a simple experience of decomposition. We can ask students to draw the decomposition in 5-groups, another name for a ten-frame configuration, but which has the advantage of emphasizing the five.
