2.NBT.7 Add and subtract within 1000, using concrete models or drawings and strategies based on place value. Differentiation: For younger students, use place value cards and base 10 materials.  Using these manipulatives have students add and find place value with mats.

1.NBT.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." This activity can be modified for gifted students by adding the number of die used. Try using two or more die as a challenge! The final score can be adjusted as well. This may be beneficial for ELL students. Instead of using 30 as the score to try to reach, try using 20. In the same way, the final score can be raised for gifted students. This activity can be used for older ages by multiplying the numbers, rather than adding them.

5.NBT.7 "Add, subtract, multiply, and divide decimals to hundredths, 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."
