Broomstick Bonanza Printable | Grade 1 Math

This Grade 1 Halloween math worksheet builds addition and subtraction fluency within 20 through 20 broomstick-themed problems, giving students structured practice that reinforces fact recall in a seasonally engaging format. Students complete equations independently after direct instruction on adding and subtracting within 20.

The worksheet features 20 addition and subtraction equations arranged in a clear, single-page layout with a Halloween broomstick theme. Students fill in missing sums and differences, working with numbers within 20. The included answer key lists all correct responses, making scoring fast for teachers or parent volunteers. No word bank or sentence frames are needed — the format is self-explanatory for first graders familiar with basic equation notation.

• Guided practice: The first several problems use smaller addends and minuends (within 10), providing an accessible entry point and reinforcing foundational fact strategies before numbers increase.
• Supported practice: Mid-set problems introduce sums and differences between 11 and 15, where students apply counting-on or make-a-ten strategies with moderate challenge.
• Independent practice: The final problems extend to the full range within 20, requiring students to recall or derive facts with minimal scaffolding, reflecting the gradual-release model (I Do, We Do, You Do).

This progression supports the gradual-release framework: teachers model strategies, students practice with support, then complete the remaining problems independently to demonstrate emerging fluency.

The primary standard is CCSS.MATH.CONTENT.1.OA.C.6: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten; decomposing a number leading to a ten; using the relationship between addition and subtraction; and creating equivalent but easier or known sums. A supporting standard, CCSS.MATH.CONTENT.1.OA.B.4, applies when students use the relationship between addition and subtraction to solve problems. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

Use this worksheet as a warm-up (before direct instruction) to assess prior knowledge of addition and subtraction facts, or as independent seat work immediately after a lesson on making-ten strategies. As students work, observe whether they count on fingers, use tally marks, or recall facts automatically — this distinction informs small-group groupings. Most first graders complete all 20 problems in 10–15 minutes.

This worksheet is best suited for Grade 1 students building toward fact fluency, and works equally well for advanced Kindergarteners or Grade 2 students who need review. It pairs naturally with a tens-frame anchor chart or a direct instruction lesson on the make-a-ten strategy. No differentiation versions are included, so teachers supporting students below grade level may wish to provide a number line alongside the sheet.

Aligned to CCSS.MATH.CONTENT.1.OA.C.6, this worksheet targets the foundational skill of adding and subtracting within 20 — a benchmark the NAEP identifies as critical for early numeracy development. Fisher and Frey (2014) emphasize that structured independent practice following explicit instruction accelerates fact fluency when problems are sequenced from simpler to more complex, precisely the pattern this worksheet follows. With 20 problems spanning accessible to challenging equations, students receive sufficient repetition to consolidate mental math strategies. The Halloween theme maintains engagement without distracting from the mathematical goal, making it appropriate for October classroom use, homework, or morning work. Teachers can use the answer key to score papers in under two minutes and record results as a formative data point toward OA.C.6 mastery.
