1st Grade Math Unit 14

Big Idea:

Coins values can be counted quickly using patterns

Student Expectations:

Priority TEKS

1.4C [Readiness] Use relationships to count by twos, fives, and tens to determine the value of a collection of pennies, nickels, and/or dimes;

Focus TEKS

1.4A [Supporting] Identify U.S. coins including pennies, nickels, dimes, and quarters by value and describe the relationships between them;

1.4B [Supporting] Write a number with the cent symbol to describe the value of a coin;

Ongoing TEKS

1.2(A-C)Number and Operations - The student applies mathematical process standards to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to: (A) recognize instantly the quantity of structured arrangements; (B) use concrete and pictorial models to compose and decompose numbers up to 120 in more than one way as so many hundreds, so many tens, and so many ones; (C) use objects, pictures, and expanded and standard forms to represent numbers up to 120.

1.3C [Supporting] Compose 10 with two or more addends with and without concrete objects;

1.3D [Supporting] Apply basic fact strategies to add & subtract within 20, including making 10 and decomposing a number leading to 10;

1.3E [Supporting] Explain strategies used to solve addition & subtraction problems up to 20 using spoken words, objects, pictorial models, and number sentences;

1.5F [Supporting] Determine the unknown whole number in an addition or subtraction equation when the unknown may be any one of the 3 or 4 terms in the equation;

1.5B [Supporting] Skip count by twos, fives, and tens to determine the total number of objects up to 120 in a set;
