Week 18 introduces rectangular arrays and repeated addition — the gateway to multiplication. Readers explore folktales and fables and notice formal vs. informal English.
Arrange crackers in a 3 × 4 array and write the matching repeated-addition sentence.

Students will build rectangular arrays with up to 5 rows and 5 columns, describe them by rows and columns, and count the total (2.OA.C.4).
3 quick questions from earlier weeks · about 3 minutes
Warm-Up
Spiral from Week 17: hand your child 12 beans and ask, 'Odd or even? Prove it.' Then say, 'Instead of two rows, make three equal rows.' Let them arrange 3 rows of 4 and notice it looks like a neat rectangle.
Mini-Lesson
Lay out 3 rows of 4 beans. Trace a finger across each row: 'Rows go across, like reading.' Trace down each column: 'Columns go up and down, like pillars.' Say, 'This is an array: 3 rows, 4 in each row, 12 in all.' Build a 2 by 5 array and a 4 by 3 array and describe each the same way. Show that an egg carton is a 2 by 6 array.
Practice
Give array cards to build with beans: 2 rows of 3, 4 rows of 4, 3 rows of 5, 5 rows of 2, 1 row of 5. For each, your child builds it, writes 'rows: __, in each row: __, total: __,' and counts. Then hunt the kitchen for arrays (muffin tin, ice cube tray, tiles, a window with panes) and record two.
Wrap-Up
Ask, 'What makes an arrangement an array?' Listen for 'equal rows and straight columns.' Add array, row, and column to the word wall.
Students will identify the lesson of a folktale and read prose aloud with accuracy and expression (RL.2.2, RF.2.4b).
3 quick questions from earlier weeks · about 3 minutes
Read-Aloud
Read 'Stone Soup' by Marcia Brown. Say that last week they compared fact books; this week they will meet the oldest kind of story, the folktale, which people told out loud long before it was written down. Ask: 'Did the soldiers trick the villagers, or teach them something?'
Mini-Lesson
Introduce three genre words on a card: folktale (an old story passed down by telling), fable (a short story with animals that teaches a lesson), and moral (the lesson). Write the moral of Stone Soup together in one sentence, such as 'When everyone shares a little, there is enough for all.'
Guided Reading
Reread the part where the villagers bring one ingredient at a time. Your child reads the villagers' lines with a different voice for each, and you keep a list of what goes into the pot. Ask why the soldiers say 'a stone soup would be better with' instead of just asking for food.
Writing Workshop
Introduce formal and informal English. Your child writes the same message two ways: a note to a friend about Stone Soup ('This book is so cool, you gotta read it!') and a note to a librarian ('I recommend Stone Soup because it teaches sharing'). Talk about which words changed and why.
Phonics: Fluency
Read story words fast and smooth: soldiers, village, hungry, hidden, stone, pot, barley, delicious, feast, clever. Your child reads the list three times while you time it, then reads one sentence from the book that contains two of the words with expression.
Students will retrace every step of the engineering design process using their own project as the example (K-2-ETS1-1, K-2-ETS1-2, K-2-ETS1-3).
Science Question of the Week
Ask: 'What are the steps an engineer follows, in order?' Let your child try from memory, then check against the notebook: ask, imagine, plan, build, test, improve, share. Note that last Friday's Design C sketch was another 'improve' step.
Investigation
Make a Design Process Path on a long strip of paper: seven stepping stones labeled with the steps, and under each glue a copy or small drawing of the matching notebook page (the problem statement, the brainstorm list, the final plan, the prototype photo, the Test Sheet, the before-and-after comic, the recommendation). Then build Design C from Friday's sketch in the remaining time, using the best parts of A and B.
Wrap-Up
Walk the path together, saying one sentence per stone about what you did. Ask: 'Which stone would you skip if you were in a hurry, and what would go wrong if you did?'
Read it aloud first while your child follows along. Then read it together, and let your child read the parts they can. Talk about the words in the word box.
A national holiday is a special day for the whole country. On many national holidays, schools and government offices close. Each holiday helps us remember a person or an event.
Independence Day is on July 4. It is our country's birthday. On July 4, 1776, American leaders approved the Declaration of Independence. Many people watch fireworks and parades.
Martin Luther King Jr. Day is in January. It honors Dr. King, who worked for equal rights for all people. He believed in peaceful ways to make change.
Memorial Day is in May. On this day we remember people in the military who died serving our country. Veterans Day is on November 11. It honors everyone who has served in the military.
Thanksgiving is in November. Families and friends often share a meal and give thanks.

| All or almost all right | Move on to Week 19. Keep the daily Remember? boxes going. |
| About half right | Build each missed array with coins or crackers and write the repeated addition under it (3 rows of 4 is 4 + 4 + 4 = 12). Also check the Unit 3 test and reteach any section where more than half was missed. |
| Only a few right | Do the catch-up activity "Rows of Buttons". Review the Unit 3 test together and reteach one section a day while Week 19 begins. |

A fox said to a crab, "You are so slow! I can win any race." The crab said, "Let us race to the rock." As the fox ran, the crab held on to his tail. At the rock, the crab let go and said, "I am here first!" The moral is: do not brag about what you can do.

Engineers ask, plan, build, test and improve
Try it (10 min): Find an array in the kitchen, like a muffin tin or an egg carton. Count the rows and how many are in each row, then say the repeated addition.
Talk about it: Does the total change if you count by columns?
Try it (10 min): Tell a fable or folktale you know from memory. Let your child tell the moral. Then say it two ways: to a friend and to a teacher.
Talk about it: Why do you think people told these stories out loud long ago?
Try it (10 min): Ask your child to show the crayon holder and tell the design steps in order. Try one small improvement together.
Talk about it: Which step helped you the most?
Try it (10 min): Look for symbols of our country around the house or on money, like a flag or an eagle. Name each one.
Talk about it: Why do you think a country has symbols?
