Multiply up to 4 digits by 1 digit and 2 digits by 2 digits.
Multi-Digit Multiplication helps fourth graders multiply bigger numbers using place value, the area model and partial products. Kids also learn to multiply by 10, 100 and 1,000 quickly, so the standard method makes sense when they meet it.

Lesson preview
This is the real lesson text your child hears, read aloud by a friendly voice.
Multiplying by 10 adds a zero: 34 × 10 = 340. By 100 adds two zeros: 34 × 100 = 3,400.
Break numbers apart: 23 × 4 = 20 × 4 + 3 × 4 = 80 + 12 = 92.
For 2-digit by 2-digit, use the area model: 21 × 13 = 200 + 60 + 10 + 3 = 273.
Estimate first: 48 × 21 is about 50 × 20 = 1,000. The answer should be close!
For parents
Learning sticks best when kids use it in real life. Here are simple ideas from this course.
Ask how many hours are in 14 days, or how many legs 23 spiders have. Let your child draw an area model to find the answer.
