Learning Objectives
Students will be able to sort objects into groups of ten and add multiples of ten to find the total number of objects.
Introduction
(5 minutes)- Seat children in a circle on the rug.
- Show students a large bag of counting objects, such as paper clips.
- Have children estimate the total number of paper clips. Explain that to estimate means to carefully guess the number of paper clips based on what they see. Record their estimations on the board.
- Discuss with students how they made their estimates.
- Explain that the class could count the paper clips one by one to determine the total number. Today they will learn a faster way to calculate the total number by sorting the paper clips in groups of 10 and then adding.
Beginning
- Give more examples of estimations, or how many there are of something more or less. For example, estimate the number of children in the school, or how many students will buy school lunch.
- Instruct students to define the vocabulary in their home language (L1). Point out the cognate estimar/estimate to Spanish-speaking students.
- Ask students to show you ten fingers.
Intermediate
- Display the sentence frame, "I think there are ________ paper clips because ________." Tell students to share an estimate with a partner using the sentence frame before choosing a few volunteers to share with the class.
