Read the following problem situations. You may need a pencil and paper. Be ready to share your solution and thinking for each one.
a) The first grade class was making bead necklaces. Tom counted 32 beads on his necklace. Rita counted 43 beads on her necklace. Lisa counted 29 beads on her necklace. List the students in order from the person who has the greatest beads to the one who has the fewest beads, and then order the number of beads from least to greatest. Use a place value model to help explain your thinking.
b) John’s book has 42 pages. Mark’s book has 35 pages. Kelly’s book has more pages than Mark’s book but fewer pages than John’s book. Use an open number line to help explain how many pages Kelly’s book could have.
