Standard:

1.1

Count, read, and write whole numbers to 100.

Standard:

1.3

Represent equivalent forms of the same number through the use of physical models, diagrams, and number expressions (to 20) (e.g., 8 may be represented as 4 + 4, 5 + 3, 2 + 2 + 2 + 2, 10 - 2, 11 - 3).

Standard:

1.2

Understand the meaning of the symbols +, -, =.

Standard:

Explain the reasoning used and justify the procedures selected.

Student Learning Objectives

Students will be able to add two numbers horizontally or vertically to sum up to ten. Students will use addition to ten in a one step problem solving. Students will learn that changing the order in an addition problem does not change the result. Students will learn key words used in addition such as total, in all, together, sum, more.

Activities

1. Students will use connecting cubes to practice addition to ten.
2. Students will make math picture dictionaries.
3. Students will line up at the front of the classroom and the teacher will help them make combinations of sums to ten.
4. Students will make flashcards with addition problems to ten.
5. Students will use calculators to practice their addition.
6. Teacher will use transparencies 2.1-2.5 of district adopted math program, Hardcourt Brace Math 1st Grade.
7. Students will use computer games such as Math Speed, Stanley's Sticky Stories, and Resource Carnival Countdown to practice their addition facts to ten.
8.Students will use worksheets from the Hardcourt Brace Mathematics student activity book.

Assessment

Students will be given a pre and post test using the math adopted text book, Hardcourt Brace Mathematics Grade 1. In addition they will be expected to complete written assignments in class and for homework. Also, teacher observation will be taken into consideration when the students participate in class or they need help to complete the assignments.

Additional Comments

I have a bilingual class this year. Most of my students are very limilted in English. Howver, I feel very fortunate to have the materials in Spanish with the exception of the computer games. Since my lesson was in mathematics and it involved mainly numbers in the computer games the students have no or very little problem using the games. They had a lot of fun using the calculators and even went ahead and tried adding numbers up to twenty and subtracting. The manipulatives helped them tremendously to visualize the concept of addition and the number value. This was not a stressful concept to teach or for the students to understand. When we got to the word problems it was easy for them to make the mathematical corrrelations. At the end of the chapter the students knew what the + and = sings meant and they knew how to use them. They also knew that when you add you put the numbers together to get one with a bigger value. Another skill that they learned was that you can reverse the order of the addends and you get the same answer. Furthermore, they learned that it doesn't matter if you add horizontally or vertically you will get the same result. The lesson as a whole was fun for the students at the same time that they learned the different skills.
