Lesson preview
This is the real lesson text your child hears, read aloud by a friendly voice.
Line up the decimal points, then add like whole numbers: 2.35 + 1.4 = 3.75.
Add zeros to help: 1.4 is the same as 1.40.
Subtract the same way: 5.2 − 1.75 = 3.45.
Money uses hundredths: 4.99 dollars + 2.50 dollars = 7.49 dollars.
For parents
Learning sticks best when kids use it in real life. Here are simple ideas from this course.
