  1. 9.5 Exploring Capacity, Symmetry, and Heights Objectives: To provide experiences comparing capacities of containers; creating a symmetrical design; and making a second height measurement. Home Link Master, page 266 EXPLORATION A Teaching Masters, Math Masters, page 264 3 containers of different sizes and shapes labeled A, B, and C a pourable substance (rice or dried beans) to fill all 3 containers EXPLORATION B Teaching Aid Masters page 265 pattern blocks Pattern-Block Template EXPLORATION C, per partnership Math Journal 2, page 184 Teaching Masters: Page 266 height stick-on notes from lesson 4.7 tape measure book Game: Math Journal 2, page 185 My Reference Book, pages 142 and 143 1 Number Grid per partnership 1 die per partnership game markers Differentiation Options: See page 763 of the Teacher's Guide

  2. Lesson 9.5 Mental Math and Reflexes Write the largest numbers you can make with these digits: 7, 2 9, 4 8, 5 1, 9 1, 5, 2 3, 3, 2 0, 9, 1 2, 5, 9 9, 1, 2 4, 9, 9 9, 8, 1 5, 5, 9 HOME LINK from yesterday, 9.4 Compare adding base-10 blocks to counting on a number grid to solve problems. Math Message Pretend that these 3 containers are filled with rice. Which container would hold the most?

  3. Capacity, capacity, the amount a container can hold.

  4. Math Masters, page 264 How Much a Container Holds

  5. My Height Record, 9.5 Math Journal 2, page 184

  6. Pattern-Block Symmetry, 9.5 Math Masters page 265

  7. Making Symmetrical Paintings Fold paper in half. Unfold the paper. Paint pictures on one half of the paper. Fold the paper, pressing the painted half and the unpainted help together while the paint is still wet. Unfold the paper. What does it mean when we say that things are symmetrical? When pictures are dry, outline the designs with markers.

  8. Measuring Capacity Observe the cup and pint containers. Remember that cups and pints are units of measure that tell how much a container holds. Watch as the substance is poured into the large bowl. Estimate how many cups fit into one pint. Check your estimates. Estimate how many cups and pints the bowl holds.

  9. Reviewing Symmetrical Shapes with Geoboards 1. Work in pairs. 2. Stretch the rubber bands around the middle column of pins on the same geoboard to create a line of symmetry. 3. Partner A uses one of the rubber bands to create half a shape on one side of the line of symmetry. 4. Partner B uses the other rubber band to complete the symmetrical shape. 5. Trade roles and create a new symmetrical shape.
