4.NBT.5 Multiply a whole number of up to four digits by a one digit whole number, and multiply two two digit numbers, using strategies based on place value and the properties of operations. Differentiation: For gifted students, and students of differing levels, the teacher could put out flashcards with multiplication factors 2-12 or create flashcards with even higher number, allowing students to do more challenging multiplication

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.

4.NBT.2 "Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons." This activity can be adjusted for ELL students by using a smaller deck of cards. The game can first be mastered by using only the black cards (positive numbers). Once the student(s) is comfortable with the concept of the game with the positive numbers, the negative numbers (red cards) can be introduced. This activity can be used for younger ages by working with only the black cards, and modeling proper mathematical words, such as "greater than" and "less than".

4.NBT.2 Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form Differentiation: For a younger group of children the recording sheet could be changed to a three digit number so that students could practice learning ones, tens, and hundreds place.
