2nd Grade - Focus Standards
MAFS.2.NBT.1.1 – Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g. 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases: a. 100 can be thought of as a bundle of ten tens – called a “hundred.” b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones). (DOK 2)
MAFS.2.NBT.1.2 – Count within 1000; skip-count by 5s, 10s, and 100s. (DOK 1)
MAFS.2.NBT.1.3 – Read and write numbers to 1000 using base-ten numerals, number names, and expanded form. (DOK 1)
MAFS.2.NBT.1.4 – Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons. (DOK 2)
MAFS.2.NBT.2.8 – Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900. (DOK 1)
MAFS.2.OA.3.3 - Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends. (DOK 2)
MAFS.2.OA.3.4 - Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends. (DOK 1)
MAFS.2.OA.2.2- Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.

1st Grade – Focus Standards
MAFS.1.NBT.1.1- Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral. (DOK 1)
MAFS.1.OA.3.5 - Relate counting to addition and subtraction (e.g., by counting on 2 to add 2). (DOK 1)
MAFS.1.OA.3.6 – Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use 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). (DOK 2)
MAFS.1.OA.2.3 - Apply properties of operations as strategies to add and subtract. 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.)(DOK 3)
