Practice drawing and labeling a place value chart (to the thousandths). Take turns drawing disks on the chart. Challenge each other to say the name of the number that was drawn.
Play the “Exponent” dice game with your child: 1. Your child rolls a die to represent an exponent. The base number is 10. 2. You ask your child to say the number in standard form. For example, your child rolls a 4. You ask, “Say 104 in standard form.” He says, “10,000.”
Practice finding the quotient with your child. You write the division sentence, and your child will say the division sentence, including the answer, in unit form. For example, 14 ÷ 2 = 14 ones ÷ 2 = 7 ones; 1.4 ÷ 2 = 14 tenths ÷ 2 = 7 tenths; 0.14 ÷ 2 = 14 hundredths ÷ 2 = 7 hundredths
Play the Decimals and Fractions card game with your child to review writing decimals as fractions: 1. Take out the jacks, queens, kings, and jokers; 2. Put the stack of remaining cards facedown; 3. Have your child flip over one, two, or three cards to represent a decimal number, as described in the examples below. Write the decimal number, and ask her to write the equivalent fraction. For example: She can flip one card to represent tenths. If she flips the number 3, you write the decimal number 0.3. She then writes the fraction 3/10 . She can flip two cards to represent hundredths. The numbers 2 and 5 represent the decimal number 0.25. The fraction is 25/100 . She can flip three cards to represent thousandths. The numbers 1, 6, and 1 represent the decimal number 0.161. The fraction is 161/1,000 .
Practice skip-counting by fractions and decimals with your child. For example, count by 2 tenths from 2 tenths to 20 tenths: 0.2, 0.4, 0.6, 0.8, 1, 1.2, 1.4, 1.6, 1.8, 2. Count by 5 tenths from 5 tenths to 50 tenths: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
