Making upProblems, Finding theAnswer After you review telling andmodeling storieswith the ReadingRug Storyboard (Unit 7MasterWorkmat), continue the activity, this time having the students say howmany bears there are in all.Make up stories involving the joining of onemore bear to the reading rug. An example: There are 4 bears on the reading rug. Onemore bear joined them on the rug. Now there are 5 bears on the rug. To help children visualize a problem as a series of steps that lead to a solution, have them look at this page one picture at a time. Give each child a blank piece of white paper, and instruct them to put it on top of the page in the book andmove it so they see only the first picture on the left side of the top row of the page. What do you see in this picture? (3 bears on a reading rug) Nowmove your piece of paper to the right until you see the next picture.What do you see here? (1 bear with a bookwalking to the rug) Nowmove your piece of paper to the right until you see the last picture. What do you see? (4 bears on a reading rug) Tellme a story about what is happening in these pictures. (First, there are 3 bears on a reading rug. Next, 1more bear comes to join them. Last, there are 4 bears on the reading rug.) Find the number cards that tell the story (3, 1, and 4). Put the numbers under the pictures at the top of this page. Have the children use the blank piece of paper again to 2 NOTE 1 look at the 3 pictures on the bottom of this page one at a time. Be sure to have the children tell thewhole story at the end, find thematching number cards, andwrite and/or put the numbers on the page.
