Lesson #  Lesson Title  Notes 

1  19.1 Introducing Two Digits  Write 10 2 digit numbers on index cards (one number on each card) and the numbers 0 to 9 on index cards (one number on each card). Put the 2digit cards in one pile face down and the singledigit cards in another pile face down. Have your student flip up one card from the 2digit pile and 1 from the singledigit pile. Have them add the two numbers writing the addition problem in their Math notebook. 
2  19.2 Comparing TwoDigit Numbers  Please take out the index cards and write numbers 0 to 20 on them (1 number on each card). Mix them up and put them in two piles. Have your student flip over two cards at a time and tell which number is greater than the other. 
3  19.3 TwoDigit Addition  Have your student practice adding twodigit numbers using a dry erase board. Give your student two sets of twodigit numbers for them to add, have them write the addition problem on their dry erase board, and solve the problem. Have them explain how they solved the problem. Continue by giving them at least 5 more addition problems. 
4  19.4 Adding 4 Numbers  Please note: On the "Feed Me" worksheet, there are no right or wrong answers. This activity allows the student to decompose the number into four numbers that will equal the total number when combined. For example, there are 13 bananas. Your student may do 10 + 0 + 2 + 1 or 3 + 4 + 4 + 2... etc. 
5  19.5 Word Problems I  Work with your student to create subtraction story problems and solve them.
