MAJOR CHANGE! You do NOT, I repeat do NOT need to

write out and submit the key terms and review questions listed in the following slides. I do, however, want you to read through them and make sure you can answer them.

Unit 29: fractions

Page 385“Even nine-year-olds have difficulty

with fractions at the symbolic level. This would indicate that for most children fraction symbols cannot safely be introduced until well into the intermediate level (grade 4 or higher).”

Unit 29: fractions

Lesson for us (class aimed at 0 to 8)?Fraction notation is NOT safe for

small children….

So we are going to limit ourselves to the following ideas: parts, wholes, halves, thirds, fourths.

After reading through the unit, make sure you can give a thorough and concise definition for the ‘key terms’ at the end of the unit. Respond to the ‘Review’ points B & C.

Unit 30: Numbers Above 10 and Place Value

• “Place value is one of the most difficult concepts for young children to grasp. Being able to rote and rational count above 10 is only a beginning step on the way to an understanding of place value.” page 399

Unit 30: Numbers Above 10 and Place Value

• Page 400“On the average, first graders can

learn to read, write and understand two-digit numbers, second graders three-digit numbers, and third graders four-digit numbers.”

What does Place Value mean?

• “Place value pertains to an understanding that the same numeral represents different amounts depending on which position it is in. For example, consider the numbers 3, 30, 300. In the first instance 3 stands for 3 1s and is in the 1s’ place. In 30, 3 stands for three 10s and is in the 10s’ place. In 300, 3 stands for three 100s and is in the 100s’ place.” page 398

Addition & subtraction from oral -> number line

This shows the commutative property of addition.

Number line

Does this work for subtraction?

Draw a number line. Solve these two problems and draw them on the number line:3 – 2 =2 – 3 =
