December: What is Grade 1 studying?
ELA:
Module 2: A Study of the Sun, Moon, and Stars
Unit Summary: In this module, students build their literacy and science skills as they engage in a study of the sun, moon, and stars. The module begins with a story about a young boy named Elvin who is curious about the sun, moon, and stars. Elvin wants to learn more about the sun, moon, and stars and shares his wonderings and artifacts he receives along his journey with the first-grade students.
Unit Tasks:
- Reading and Answering Questions about Kitten's First Full Moon
- Science Talk Discussing Observable Patterns in the Sky
- Using Observations of the Sun to Write a Narrative Poem
Eureka Math:
Module 2: Introduction to Place Value Through Addition and Subtraction Within 20
Students will...…
- solve word problems with three addends
- use the associative and commutative property
- make a ten
- compare efficiency of counting on
- model subtraction from teen numbers
Common Core Learning Standards:
1. OA.A.1 - Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
1.OA.A.2 - Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
1.OA.B.3 - Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
1.OA.B.4 - Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8.
1.OA.C.6 - Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
1.NBT.B.2 - Understand that the two digits of a two-digit number represent amounts of tens and ones.
