    Show a partitioned rectangle with 4 rows of 5 and ask, 'How many rows? How many columns? What is the total?' Then ask for the repeated addition sentence for the rows.

    15 min

    Review Mini-Lesson

    Review the rules together: squares must be the same size, lines go straight across and straight down, rows go across, columns go up and down. Have your child find one mistake in a rectangle you draw with uneven squares and fix it.

    15 min

    Weekly Assessment

    Your child draws and partitions with a ruler: a rectangle with 3 rows and 4 columns, and a rectangle with 2 rows and 5 columns. For each they write the total number of squares and a repeated addition sentence. Then they count the squares in a pre-drawn 4 by 4 rectangle you provide.

    5 min

    Wrap-Up

    Reflect: 'Where in our house did you see rows and columns this week?' Preview next week: 'We will cut shapes into equal shares to split food fairly.'

    Art Connection: Protect Our Habitat Sign

    Your child designs a sign for a real place you visit (a park, a creek, your own yard): a big picture of one animal that lives there, a short message such as 'Keep our pond clean for the frogs,' and a drawing of the pond protector design. Make it on card stock and, if it is your own yard, post it on a stick by the garden.
