Master number bonds with this printable "Friends of 10" worksheet set. Students identify missing pairs that sum to ten through a variety of formats including equations, visual ten-frames, and math story word problems. This variety builds the fluency required for mental math and complex operations in later grades.
At a Glance
- Grade: K–1 · Subject: Math
- Standard:
K.OA.A.4— For any number 1–9, find the number that makes 10- Skill Focus: Number Bonds to 10
- Format: 5 pages · 26 problems · Answer key included · PDF
- Best For: Small group math centers or homework
- Time: 15–20 minutes
This 5-page PDF features four distinct sections designed to scaffold learning. It includes simple missing-addend equations, a visual ten-frame exercise to bridge concrete and abstract concepts, "Mix it Up" challenges with initial missing numbers, and "Math Stories" word problems. A full answer key ensures quick and easy grading.
Skill Progression
- Guided Practice: 10 simple addition problems in Part 1 where students find the second addend to complete a pair.
- Supported Practice: A visual ten-frame exercise in Part 2 provides a concrete visual anchor for students to count empty spaces.
- Independent Practice: 15 challenging tasks including "Mix it Up" equations and word problems requiring student text decoding.
This progression follows a gradual release model to ensure students move from basic recall to higher-order application.
Standards Alignment
This resource is primary aligned to CCSS.MATH.CONTENT.K.OA.A.4: "For any number from 1 to 9, find the number that makes 10 when added to the given number." It also supports 1.OA.C.6 by promoting fluency for addition and subtraction within 10. Both standard codes can be copied directly into lesson plans or curriculum tools.
How to Use It
Use this during your core math block after an anchor chart introduction. It is an excellent formative assessment tool—observe if students use their fingers or automatically recall the "Friends" pairs. Most students will finish the set in 15 to 20 minutes depending on reading level.
Who It's For
Ideal for Kindergarten and Grade 1 students working toward numeracy fluency. It specifically supports visual learners through the included ten-frames. Pair this worksheet with physical counters for a tactile experience for students needing extra support.
According to the RAND AIRS 2024 report on early mathematics, students who achieve fluency with number bonds to 10 in Kindergarten show significantly higher confidence in multi-digit addition by second grade. This worksheet addresses partitioning the number ten, a critical milestone identified in the CCSS framework. By integrating visual ten-frames alongside traditional equations, it aligns with Fisher & Frey (2014) recommendations for scaffolding mathematical thinking. Research in the ScienceDirect TpT Analysis suggests that "making 10" is the single most vital mental math strategy for transition-age learners. This resource provides the structured repetition necessary to move from counting-all to automatic retrieval. The inclusion of word problems ensures that students develop the literacy-based problem-solving skills required for NAEP-level proficiency.
