In class today, children used blocks to make the mirror image of a design across a line of symmetry. This resulted in a symmetrical design. A figure is symmetrical across a line if it has two matching halves. On this page, help your child complete the designs so that they are symmetrical. Please return this Home Link to school tomorrow.

In Unit 8, we worked with unit fractions, such as 1 2 , 1 3 , and 1 4 . Today, we started to explore fractions in which the number above the fraction bar is more than 1, such as 2 3 , 3 4 , and 5 6 . If your child is having trouble with some of the problems on this page, you might mention that 1 2means that 1 out of 2 parts is shaded, that 3 6means that 3 out of 6 parts are shaded, and so on. Or you might ask your child to explain the fractions to you in this way. Please return this Home Link to school tomorrow.

Today we divided unit strips into equal parts: halves, thirds, fourths, sixths, and eighths. Then we compared the sizes of the parts. Your child probably cannot tell which of two fractions is more by looking at the fractions, but he or she should be able to compare two fractions by looking at pictures of them. Encourage your child to label one part of each shape with a fraction before deciding which fraction is more or less. Please return this Home Link to school tomorrow.

This Home Link reviews some of the fraction concepts we have covered this year. The most important concept first graders should understand is that a fraction names a part of something (the whole) that has been divided into equal parts. Because children’s work on fraction concepts this year may be their first exposure, they may still be unclear about some of the ideas we have explored. That’s okay; these and other fraction concepts will be revisited in later grades. Please return this Home Link to school tomorrow. Family Note HOME LINK 9 8 Name Date Solving Fraction Problems 1.

Name Date Unit 10: Family Letter End-of-Year Reviews and Assessments In Unit 10, children will review the concepts and skills they have learn\ ed throughout the year. Children will review ways to make sense of collections of data, such a\ s height measurements. Specifically, they will use the data they collected at the beginning of the year to determine how much they have grown during the last few month\ s. Children will also continue to use mental math strategies to solve numbe\ r stories involving money. Finally, children will review the following skills: Telling time to 5 minutes on an analog clock  Using straws to construct geometric figures  Reading and comparing temperatures on a thermometer  Understanding place-value concepts  Using the number grid 276 Copyright © Wright Group/McGraw-Hill HOME LINK 99 100 90 80 70 60 50 40 30 20 10 0  10  20  30  40  50  60 210 200 190 180 170 160 150 140 130 120 110 100 90 80 70 60 50 40 30 20 100  10  20  30  40  50  60  70  80  90 10 °C °F

Copyright © Wright Group/McGraw-Hill 277 Do-Anytime Activities To work with your child on the concepts reviewed in this unit, try these interesting and rewarding activities: 1.Continue to work on telling time to the minute. 2.Ask for answers to number stories that involve two or more items. For example, I want to buy a bran muffin for 45 cents and a juice box for 89 cents. How much money do I need? ($1.34) Encourage your child to use mental math, coins, the number line, or the number grid to work out solutions. 3.Point to a 3-digit number, such as 528. Ask what the digit “2” means (20); the “5” (500); the “8” (8). 4.Have your child create the largest and smallest numbers given 2 or 3 digits. 5.Together, note the temperature when the weather feels too hot, too cold, or about right. Encourage your child to read any temperature sign or billboard when you travel, noting whether the degrees are Celsius or Fahrenheit. Unit 10: Family Letter cont.
