StandardFluently add within 1000
|
Core Standard3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
|
In Other Words...Students will learn to solve addition equations using strategies like using a hundreds chart, place value blocks, place value partial sums and partial differences (adding the hundreds, then the tens, then the ones), estimation, and drawn representations.
|
If MasteredStudents can demonstrate proficiency by adding and subtracting all whole numbers with or without regrouping. The following is a link to activities that extend this learning: http://ccssmath.org/?page_id=364

StandardMultiply numbers by multiples of 10.
|
Core Standard3.NBT.3 Multiply one-digit whole numbers by multiples of 10 in the range 10–90 using strategies based on place value and properties of operations.
|
In Other Words...9x8=72 therefore, 9x80=720 7x2=14 therefore, 7x20=140
|
If MasteredStudents may multiply one-digit whole numbers by multiples of 100, 10,000 and 100,000. This may be demonstrated by creating flashcards. The flashcards can be used to build speed and fluency with the extended multiples.
