## Learning Coach Notes:

Lesson # Lesson Title Notes
1 21.1 Subtraction Get a set of subtraction flashcards, mix them up and see how many your student can answer. For every fact they get correct, give them the card. For every fact they get wrong, you keep the card. The person with the most cards at the end wins.
2 21.2 Parts of a Fraction Get pizza this week for lunch or dinner. Talk about the different fractions you can make from the pizza. Have your student write down the fractions they talked about and identify the numerator and denominator.
3 21.3 Denominators Draw a few different shapes and divide them into equal parts. Shade in a certain amount of parts for each shape you drew. Have your student identify the denominator for a fraction of each shape and then identify the numerator for the shaded amount.
4 21.4 Numbers through Nineteen In their math notebook, have your student use different colored crayons or markers and write the numbers 0 to 19 using different colors.
5 21.5 Two Digit Subtraction I Get a deck of cards and remove all face cards, jokers and aces. Shuffle the cards and create 2 piles. Put the piles in front of your student. In the pile on the left, have your student draw 2 cards and write the number down (so if they draw a 2 and a 4, they would write 24). In the pile on the right, have them draw 1 card and write the number below their 2-digit number putting the single digit in the one's column. So if they drew 3, they would write the subtraction problem 24-3. Have them solve the problem. Have them repeat these steps until they have gone through all of the cards.

## Module Guiding Questions:

When a student starts a lesson ask them questions to check for prior knowledge and understanding and to review concepts being taught. At the end of the lesson ask the questions again to see if their answer changes.

## Module Video Questions:

When a student watches a video take time to ask them questions about what they watched. Suggested questions for the videos in this module are listed here. Suggestion: Have the student watch the entire video first all the way through. Then have them watch the video a second time, as they watch it pause the video and ask the questions.

## Module Suggested Read Aloud Books:

Take time to read to your student or have them read aloud to you. Read a different book each day. While reading the book point out concepts being taught. You may purchase these books or find them at your local library. Suggested things to discuss while reading the book:

• What is the main idea?
• What are three things new you learned?
• How does this book relate to what you are learning about?
