このクラスで学べること
In this class I will be teaching the third quarter of 1st grade math. I will be using the common core standards along with other methods to help students fully understand the how and why of math. Students will learn different ways to solve a problem then can choose the way that is best for them. ***This class will only run if there are at least 2 students. In this class students are encouraged to ask questions and discuss and explain problems. Students will get many opportunities to participate in this class. My goal is to help my students love math. Week 1: REVIEW DAY: ( Review skills learned in the first 16 weeks) Module 2 Lesson 12: Solve word problems with subtraction. Lesson 13: Solve word problems with subtraction. Week 2: Lessons 14: Model subtraction of 9 from teen numbers. Lesson 15: Model subtraction of 9 from teen numbers. Lesson 16: Relate counting on to making ten and taking from ten. Lessons 17: Model subtraction of 8 from teen numbers. Lesson 18: Model subtraction of 8 from teen numbers. Lesson 19:Compare efficiency of counting on and taking from ten. Week 3: Lesson 20: Subtract 7, 8, and 9 from teen numbers. Lesson 21:Share and critique peer solution strategies for take from with result unknown and take apart with addend unknown word problems from the teens. Lesson 22: Solve put together/take apart with addend unknown word problems, and relate counting on to the take from ten strategy Week 4: Lesson 23: Solve add to with change unknown problems, relating varied addition and subtraction strategies. Lesson 24: Strategize to solve take from with change unknown problems. Week 5: Lesson 25: Strategize and apply understanding of the equal sign to solve equivalent expressions. Lesson 26: Identify 1 ten as a unit by renaming representations of 10. Week 6: Lesson 27: Solve addition and subtraction problems decomposing and composing teen numbers as 1 ten and some ones. Lesson 28: Solve addition problems using ten as a unit, and write two-step solutions. Lesson 29: Solve subtraction problems using ten as a unit, and write two step solutions. Module 2 Assessment Week 7: Module 3 Lesson 1: Compare length directly and consider the importance of aligning endpoints. Lesson 2: Compare length using indirect comparison by finding objects longer than, shorter than, and equal in length to that of a string. Lesson 3: Order three lengths using indirect comparison. Week 8: Lesson 4: Express the length of an object using centimeter cubes as length units to measure with no gaps or overlaps. Lesson 5: Rename and measure with centimeter cubes, using their standard unit name of centimeters.
学習到達目標
Represent and solve problems involving addition and subtraction.
1.OA.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.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.
Understand and apply properties of operations and the relationship between addition and
subtraction.
1.OA.3 Apply properties of operations as strategies to add and subtract. (Students need not use
formal terms for these properties.) 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.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by
finding the number that makes 10 when added to 8.
Add and subtract within 20.3
1.OA.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
Use mental 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).
Understand place value.4
1.NBT.2 Understand that the two digits of a two-digit number represent amounts of tens and ones.
Understand the following as special cases:
a. 10 can be thought of as a bundle of ten ones—called a “ten.”
b. The numbers from 11 to 19
Students will need a paper and pencil for each class.

Hi, my name is Madison. I have a Bachelor's of Science Degree in Elementary Education with an emphasis in Social Science and Math. I have a 9 year old son and a 6 year old daughter. We love to play outside and create art with the things we find in nature. I believe that children should have a passion for learning. So let's make things FUN and INTERESTING!レビュー
