Baking Champions: Subtract Your Way to Glory

About this Grade 1 Subtraction Drill

Subtraction is one of the first big mathematical ideas your child encounters, and it builds the foundation for all math ahead. At age 6 or 7, students are developing the ability to decompose quantities—to understand that a group can be broken apart—which is essential for number sense and problem-solving. When children learn to subtract, they're practicing how to take away, compare amounts, and think backwards from a total. This skill shows up everywhere in daily life: when you eat some cookies and count what's left, when you share toys and figure out who has fewer, or when you're baking-champions in the kitchen measuring out ingredients. Subtraction also strengthens working memory and builds confidence with numbers, helping children see themselves as capable mathematicians. Most importantly, subtraction teaches children that numbers are flexible and can be taken apart in different ways.

What your student will practice

• Take away objects from a group and count what remains
• Solve subtraction problems within 10 using concrete strategies
• Recognize and write subtraction number sentences with the minus symbol
• Use pictures and numbers together to show subtraction situations

Common mistakes to watch for

The most common error at this age is counting incorrectly after removing objects—for example, a child might cross out 3 items from a group of 7 but then count the remaining objects starting at 1 again, or skip a number in the counting sequence. Another frequent mistake is confusing the direction of subtraction; students sometimes subtract the larger number instead of the smaller one because they haven't internalized what "take away" means. You'll spot this when a child writes 3 – 7 instead of 7 – 3, or when they count backwards but lose track partway through. Watch for hesitation around the minus symbol itself—some children don't yet understand it represents "taking away" rather than just a separator.
