Type: Lesson/Unit Plan

Overview:

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).

Unpacked Content Evidence Of Student Attainment:Students: Count correctly from 0 to 100 by ones without skipping numbers, repeating numbers, or hesitating. Count correctly from 0 to 100 by tens without skipping numbers, repeating numbers, or hesitating. Count backwards from 10 to 0 by ones without skipping numbers, repeating numbers, or hesitating.Teacher Vocabulary:Count forward orallyCount backwards orallyKnowledge:Students know: how to count by ones and tens orally. This includes counting forward and counting backward.Skills:Students are able to: orally count forward. orally count backward.Understanding:Students understand that: Counting from 0 to 100 is a sequence. Alabama Alternate Achievement Standards AAS Standard: M.AAS.K.1 Using vocalization, sign language, augmentative communication, or assistive technology, count to 15 by ones starting with one. Mathematics MA2019 (2019) Grade: K 14. Compose and decompose numbers from 11 to 19 by using concrete objects or drawings to demonstrate understanding that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones. Unpacked Content Evidence Of Student Attainment:Students: Given any two-digit number from 11 and 19, use drawings or concrete objects to show and explain the decomposition of the number into one group of 10 and the correct number of ones. Teacher Vocabulary:Compose DecomposeKnowledge:Students know: the number sequence to 19. Strategies to decompose a number into tens and ones.Skills:Students are able to: Use objects to compose and decompose numbers.Understanding:Students understand that: ten things can be represented as one ten or as ten ones. Alabama Alternate Achievement Standards AAS Standard: M.AAS.K.14 Compose numbers from 11-15 by using concrete objects or drawings to demonstrate understanding that these numbers are composed of ten ones and one, two, three, four, or five ones.
