    Mini-Lesson: Taking Lengths Away

    Read: 'A rope is 50 feet long. Dad cuts off 23 feet to make a swing. How much rope is left?' Draw a 50 bar, shade the 23 part that is cut away, and write 50 - 23 = ? (27 feet). Then read a comparison problem: 'Lena jumped 42 inches. Ben jumped 35 inches. How much farther did Lena jump?' Draw two bars lined up at the left, and write 42 - 35 = 7 inches.

(35 cm). 2: 'A snake is 58 inches long. A lizard is 21 inches long. How much longer is the snake?' (37 inches). 3: 'A hallway is 90 feet. Sam has walked 47 feet. How many more feet until the end?' (43 feet). Support: act out problem 1 with real string and scissors. Stretch: write a fourth subtraction length problem and solve it.

    Read the second half of 'Penguins!' (nests, eggs, chicks, dangers). Your child reads the labels on the diagrams while you read the paragraphs. Ask 'How does a father emperor penguin keep the egg warm?' and 'Why do chicks huddle?' and have your child put a finger on the sentence that answers each.

Your child reads the pairs, then writes four sentences about penguins and their neighbors using at least three irregular plurals (for example, 'Penguins have two feet and no teeth.'). Support: provide sentence frames with the plural blank. Stretch: add two more pairs they know (mouse and mice already given, so try 'person, people' and 'leaf, leaves').

    I can subtract lengths to find what is left or how much longer.

    Look: 60 cm − 24 cm

    1. Draw a bar for 60 cm.
    2. Shade the 24 cm part that is cut off.
    3. Subtract: 60 − 24 = 36. There are 36 cm left.

    Draw a bar model. Write an equation. Write the answer with the unit.

    1. A ribbon is 72 inches long. Mia cuts off 35 inches. How much ribbon is left?
    2. A red fence is 81 feet long. A white fence is 46 feet long. How much longer is the red fence?
