This Fluency Activity is a part of the Lesson 10, Unit 3, Grade 2. Display and label a penny and a dime. At the signal, say the answer. A penny is like 1 one, 1 ten, or 1 hundred? Coin names are important and take time for English language learners to learn. It is wise to have a classroom economy (search online under classroom economies for children) using coins so that they are used again and again.
