Max Rescues the LEGO City: Doubles Facts Race

About this Grade 1 Doubles Facts Drill

Doubles-facts—knowing that 2+2=4, 3+3=6, and 5+5=10—form the backbone of early addition fluency. At age 6-7, your child's brain is developing the ability to recognize patterns and store math facts in working memory, skills that make learning feel less like counting on fingers and more like instant recall. When students master doubles, they build confidence that spills into all of math: they solve word problems faster, they recognize related facts (like 5+5=10 means 5+6=11), and they develop number sense that lasts. Doubles are also the easiest facts to visualize—imagine two matching stacks of blocks, or two hands holding the same number of fingers—making them the perfect entry point to automaticity. By drilling these eight core facts now, you're giving your child a toolbox for multiplication, fractions, and mental math strategies they'll use for years.

What your student will practice

• Recall and state doubles-facts (1+1 through 10+10) with automaticity
• Recognize patterns in doubles and explain why they work
• Apply doubles-facts to solve word problems and related addition situations
• Use doubles-facts to find sums of near-doubles (like 5+6 using 5+5)

Common mistakes to watch for

The most common error is confusing the double with the number itself—a child will say '3+3=3' instead of '3+3=6,' often because they're still thinking of the number rather than the sum. Watch for hesitation or finger-counting on every double, which signals the fact hasn't been stored in memory yet. Another red flag is mixing up doubles with different numbers, like saying '4+4=8' correctly but then saying '4+5=8' with equal confidence. If you see these patterns, the child needs more practice with the specific fact through repetition and visual models.
