Kindergarten Math Unit 3

Big Idea:

Students will write and represent 16-20, count by 1s orally to 50, add to 10, organize data into groups for graphing, and compare (greater than/less than) up to 10.

Student Expectations:

Priority TEKS

K.2 (I) [Readiness] compose and decompose numbers up to 10 with objects and pictures

Focus TEKS

K.2(B) [Readiness] read, write, and represent whole numbers from 0 to at least 20 with and without objects or pictures

K.2(C) [Supporting] count a set of objects up to at least 20 and demonstrate that the last number said tells the number of objects in the set regardless of their arrangement or order

K.2(E) [Supporting] Generate a set using concrete and pictorial models that represents a number that is more than, less than, and equal to a given number up to 20

K.2(F) [Supporting] Generate a number that is one more than or one less than another number up to at least 20

K.2(G) [Supporting] compare sets of objects up to at least 20 in each set using comparative language

K.2(H) [Readiness] use comparative language to describe two numbers up to 20 presented as written numerals

K.3(A) [Supporting] Model the action of joining to represent addition and the action of separating to represent subtraction

K.3(B) [Readiness] Solve word problems using objects and drawings to find sums up to 10 and differences within 10

K.3(C) [Supporting] Explain strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences

K.5 [Supporting] recite numbers up to at least 100 by ones and tens beginning with any given number (count orally to 50 by 1’s)

Ongoing TEKS

K.2(B) [Readiness] read, write, and represent whole numbers from 0 to at least 20 with and without objects or pictures

K.8(A) [Supporting] Collect, sort, and organize data into two or three categories

K.8(B) [Readiness] Use data to create real-object and picture graphs

K.8(C) [Readiness] Draw conclusions from real-object and picture graph

Student Learning Targets:

• I will write numbers 16-20 using lined paper.
• I will count from 0-50 by saying each number out loud.
• I will show the numbers 16-20 using manipulatives (counters, linking cubes, etc.).
• I will add sums up to 10 using objects and pictures.
• I will organize data into groups for graphing.
• I will compare sets up to 10 using comparative language (more, less, the same).

Essential Questions:

• When you count, what number comes before/after? (0-20)
• How do you count and write ____ with words and numbers?
• Which group as more? Less?
• How do you know if groups are equal or the same?
• What is a number that is 1 more/1 less than ____ ? (0-20…orally)
• How can you sort objects into categories?
• Describe how the items fit into categories?
• How can you make a real-object graph to count objects that have been sorted into categories?
