Learning Coach Notes:

Lesson # Lesson Title Notes
1 22.1 Two-Digit Subtraction II Get a set of cards and remove the face cards, aces and jokers. Shuffle the cards and place them face down in a pile. Have your student draw 2 cards and make a 2-digit number from those 2 cards. Then, you draw 2 cards and make a 2-digit number from your cards. Have your student write a subtraction problem using the 2-digit numbers you both created from the cards and solve the problem. Repeat these steps until the pile is done.
2 22.2 Missing Numbers On index cards, write the numbers from 5 to 100 in 5's, for example, 5, 10, 15, 20, 25, etc.(1 number on each index card). Have your student put the cards in order from 5 to 100. Have them close their eyes and remove 5 cards from random spots. Have your student guess which numbers are missing. Repeat this multiple times.
3 22.3 Recognizing Numbers by 10's In their math notebook have your student use different colored crayons or markers to write their 10's from 10 to 100 (10,20,30,40,50,60,70,80,90,100).
4 22.4 Adding 4 One-Digit Numbers Get a deck of cards and remove the face cards, jokers and aces. Mix up the cards and place them face down in a pile. Have your student draw 4 cards and add those 4 numbers together in their Math notebook. Have them repeat this procedure until all cards are gone from the pile.
5 22.5 Picture Graphs Please have your student choose a topic to make a pictograph for (for example, their family's or friend's favorite food, color, snack, tv-show, sport, etc.) and make a pictograph showing their results in their Math notebook.

Module Guiding Questions:
