Over 180 pages of differentiated math centers to address the needs of Kindergarteners, First Graders, and Second Graders.
The centers address the Numbers and Operations in Base Ten and Numbers and Operations in Algebraic Thinking Domains.
The centers address the following standards:
K.OA.2 Add and subtract within 10.
K.OA. 3 Decompose numbers less than or equal to 10 into parts in more than one way.
1.OA.3 Apply properties of operations as strategies to add and subtract.
1.OA.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false.
1.OA.8 Determine the unknown whole number in an addition and subtraction equation.
K.CC.5 Count to answer how many questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration.
K.NBT.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones. (use equations)
1.NBT. 2 Understand that the two digits of a two-digit number represent amounts of tens and ones.
a. 10 can be thought of as a bundle of ten- called a “ten”
b. The numbers 11-19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
c. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, nine tens (and 0 ones).
2.NBT.1 Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones.
K.CC.6 Identify whether the number of objects in one group is greater than, less than or equal to the number of objects in another group.
1.NBT.3 Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, <, =
2.NBT.4 Compare two three-digit numbers using strategies based on place vale and properties of operations.
K. OA. 4 For any number 1 to 9, find the number that makes 10 when added to the given number.
1.NBT.4 Add within 100, including a two-digit number and one-digit number and adding a two-digit number and multiple of ten
1.NBT.5 Given a two-digit number mentally find 10 more or 10 less, without having to count.
1.NBT.6 Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90.
2.OA.7 Add and subtract within 1000.
2.NBT.6 Add up to four two-digit numbers using strategies based on place value and properties of operations.
The centers include "I Can Cards," material lists, and procedures for the teacher.
