In Module 5, Topic A, students count two separate parts within teen numbers, 10 ones and some ones. They start by counting piles of 10 straws to understand 10 ones. In Lesson 2, students separate 10 ones and some ones from within teen quantities using an egg carton cut off to have 10 compartments. Continuing with decomposing, in Lesson 3, students circle 10 ones within teen quantities at the pictorial level. In Lessons 4 and 5, students count their 10 ones and some ones to 20 the Say Ten way (e.g., ten one, ten two, ten three, ten four, ten five, ten six, ten seven, ten eight, ten nine, 2 ten).
