Warm-Up

Last week ended with equal shares, so start with a quick bridge: fold one paper into halves and one into fourths, then ask which piece is bigger. Then write 38 + 25 and 62 + 19 on the board and have your child solve both mentally, saying the strategy out loud (make a ten, add tens then ones).

Mini-Lesson

Introduce Unit 6: 'For the next six weeks we are visiting every big idea from the year, and at the end you will plan a class picnic using all of it.' Review two-step addition problems (first taught Week 13): 'Maya had 27 stickers. She got 15 more on Monday and 8 more on Tuesday. How many now?' Model a bar model with three parts, write 27 + 15 + 8 = ?, and solve by adding 27 + 15 = 42, then 42 + 8 = 50.

Practice

Your child solves three problems with a bar model and an equation for each: 'A jar has 46 beans. Dad adds 23, then Grandma adds 9. How many beans?' (78). 'Leo read 18 pages, then 24 pages, then 12 pages. How many pages?' (54). 'A bus had 35 riders. 17 got on at the park and 6 got on at the library. How many riders?' (58). Check that the model matches the story before checking the answer.

Wrap-Up

Start the Unit 6 math portfolio: label a folder 'My Grade 2 Math' and put today's best bar model inside. Ask: 'Which step did you do first, and how did you know?'

Read-Aloud

Read 'A List' from Frog and Toad Together by Arnold Lobel. Before reading, say: 'Way back in Week 1 we learned that good readers ask questions. Keep one who, one what, and one why question in your head.' Stop after Toad's list blows away and have your child ask you one of the three questions out loud.

10 min

Mini-Lesson

Write the six question words (who, what, where, when, why, how) on index cards and lay them in a row. Model answering 'Why can't Toad do anything after the list blows away?' by pointing to the exact page and reading the line that proves it. Say: 'An answer from the book beats an answer from my head.'

15 min

Guided Reading

Your child rereads 'A List' aloud, then draws one question card at a time and answers each with a finger on the page. Record answers on a 'Question and Answer' page in the reading notebook, in complete sentences.

Writing Workshop

Genre review, day one: narrative (first taught in Week 3 and Week 25). Your child makes a list, just like Toad, of five things that happened yesterday, then circles the most interesting one to become this week's small-moment story. Have them write the first two sentences today, telling who was there and where it happened.

10 min

Phonics

Vowel team review from Week 2 (ai, ay, ee, ea). Dictate: rain, stay, sleep, meal, wait, play, green, dream. Your child writes each, underlines the team, and reads the list back at speed.

Science Question of the Week

Ask: 'Last week we learned how animals are adapted to survive. What does a living thing need to do to keep its kind going?' Write the word 'life cycle' on an index card and say: every living thing is born, grows, makes new living things, and dies, and the circle starts again.

20 min

Investigation

Fold a damp paper towel, tuck 4 dried beans (pinto or kidney from the pantry) inside, and slide it into a zip bag taped to a sunny window. Have your child draw the bag and beans on day 1 of a 'Bean Diary' page and write the date. Then lay out 4 index cards labeled seed, sprout, plant with flowers, plant with seed pods and have your child arrange them in a circle with arrows, explaining what happens at each arrow.

5 min

Wrap-Up

Ask: 'Why do I draw the arrows in a circle instead of a straight line?' Listen for the idea that the last stage makes new seeds and the cycle repeats. Support: give the sentence frame 'The seed pods make new ____.' Stretch: ask what would happen to the cycle if bees never visited the flowers, linking back to pollination from Week 11.
