3.2 Multiplying and dividing

To multiply and divide by 10, 100, 1000, etc., write the digits in their place value columns. To multiply, move the digits to the left (replacing the numbers on the right with zeros) and to divide move them to the right (putting in a decimal point, and any zeros necessary for the place value).

Multiplication and division by whole numbers in general can be carried out by combining this technique with a knowledge of the multiplication tables up to 10.

Worship service for the Sixth Sunday After Pentecost. How does God distinguish good from evil? The story of Jacob in Genesis challenges common understandings of what we may commonly understand as "good" in that Jacob is set apart to bear the promise of God despite his capacity for deceit and trickery. In the gospel lesson from Matthew, Jesus tells the parable of the wheat and the weeds. This parable suggests that the seeds of evil and good can grow up together and be difficult to distinguish.
