STUDENT LEARNING GOALS
Mathematics Standards (Appendices A & B)
1.NBT.B.2a:
10 can be thought of as a bundle of ten ones — called a "ten."
1.NBT.B.2c: The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six,
seven, eight, or nine tens (and 0 ones).
1.NBT.B.3: Compare two two-digit numbers based on meanings of the tens and ones digits,
recording the results of comparisons with the symbols >, =, and <.
1.NBT.C.4: Add within 100, including adding a two-digit number and a one-digit number, and adding
a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on
place value, properties of operations, and/or the relationship between addition and subtraction;
relate the strategy to a written method and explain the reasoning used. Understand that in adding
two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to
compose a ten.
(Include MP1 and MP6 for all units for 2014-2015)
MP1: Make sense of problems and persevere in solving them.
MP6: Attend to Precision
