Describe, model, and classify shapes and figures using applicable properties. Experiment with shapes and figures to make generalizations regarding congruency, symmetry, and similarity. Use transformations such as slides, flips, and rotations. Use the properties of shapes and figures to describe the physical world. Create symmetrical designs with pattern blocks and indicate the lines of symmetry.
Measurement is valuable as an integrating skill throughout the curriculum and in everyday life.
The use of estimation is vital in determining the reasonableness of measurement. Estimate and measure length, time, temperature, weight, and capacity. Identify and give the value of different coins. Select standard and non-standard tools for determining length, time, temperature, weight, and capacity, and use them to solve every day problems. Solve and justify solutions to real-life problems involving the measurement of time, length, area, perimeter, weight, temperature, mass, capacity, and volume.
