    Math

    Students will write two repeated addition equations for one array, adding by rows and by columns, and show both give the same total (2.OA.C.4).

    Activities

    Warm-Up

    Flash cards with quick repeated addition: 2 + 2 + 2, 5 + 5 + 5 + 5, 3 + 3 + 3 + 3, 4 + 4, 10 + 10 + 10. Your child answers and names the matching skip count.

    15 min

    Mini-Lesson

    Build 3 rows of 5 beans. Add by rows: 5 + 5 + 5 = 15. Now turn the paper sideways so the columns become rows and add by columns: 3 + 3 + 3 + 3 + 3 = 15. Say, 'Same beans, two equations, same total.' Repeat with 2 rows of 4: 4 + 4 = 8 and 2 + 2 + 2 + 2 = 8. Ask which equation is quicker to write and why.

    15 min

    Practice

    For four arrays (4 by 3, 2 by 5, 5 by 4, 3 by 3) your child builds each, writes the by-rows equation and the by-columns equation, and circles the total. Then draw a 4 by 5 array on grid paper and write both equations (5 + 5 + 5 + 5 = 20 and 4 + 4 + 4 + 4 + 4 = 20). Support: build only 2 by 3 and 3 by 2 with beans and physically rotate them. Stretch: draw a 5 by 5 array and write both equations, then explain why they look the same.

    5 min

    Wrap-Up

    Ask, 'If I turn an array sideways, does the total change?' Listen for 'no, the same beans are still there.'

    Read-Aloud

    Read 'Anansi the Spider: A Tale from the Ashanti' by Gerald McDermott. Explain that this folktale comes from the Ashanti people of Ghana in West Africa and explains how the moon got into the sky. Ask: 'Which of the six sons did the most to save Anansi? Why could Anansi not choose?'

    Mini-Lesson

    Add Anansi to the Morals chart and compare: Stone Soup and Anansi both show that a group does what one person cannot. Show that this folktale also explains something in nature (the moon), which fables do not do. Support: you name the story, your child names the moral. Stretch: they explain why Anansi is a trickster and the Hare is not.

    Guided Reading

    Reread the six sons' pages with your child reading each son's name and job in a strong, even beat (See Trouble, Road Builder, River Drinker, Game Skinner, Stone Thrower, Cushion). Point out that the repeating pattern reads like a poem, and have them clap the beat on a second read.

    Writing Workshop

    Your child revises their fable from yesterday, then rewrites its moral two ways, informal ('Don't brag, you'll lose!') and formal ('Boasting often leads to losing'). They choose which one fits the end of a fable and explain why.

    Phonics: Fluency

    Poetry fluency: return to 'Where the Sidewalk Ends' from Week 13 and have your child read 'Hug O' War' aloud twice, once for accuracy and once for beat. Word list to warm up first: son, spider, trouble, river, moon, forest, cushion, globe, sky, night.

    Deeper Investigation

    Build a trifold showcase board from a cut cereal box or three taped sheets. Left panel: the Problem Brief and 'before' picture. Middle panel: the three prototypes' names with the Comparison Table and the picture graph. Right panel: the recommendation sentence and the Design Process Path. Practice a two-minute talk that starts with 'Our problem was' and ends with 'We recommend', and time it.

    I can add the rows and the columns of an array and get the same total.

    Look: 2 rows of 3

    1. By rows: 3 + 3 = 6.
    2. Turn it sideways. By columns: 2 + 2 + 2 = 6.
    3. Same dots, two equations, same total.

    Draw each array. Write the rows equation and the columns equation.

    1. 5 rows of 2. Rows: ____ Columns: ____
    2. 2 rows of 5. Rows: ____ Columns: ____
    3. 3 rows of 2. Rows: ____ Columns: ____
    4. 2 rows of 4. Rows: ____ Columns: ____
