Each day includes the materials you need, the actual activity script, a quick neurodivergent-friendly tip, and a simple way to check understanding. No need to teach all 5 days back to back - pace it to your class._ Number bonds - the idea that a number can be split into two parts that together make the whole - are one of the most useful early building blocks in math. Once a student can flexibly see that 8 is "5 and 3" or "6 and 2," addition and subtraction within 20 stop being separate skills and start feeling like two views of the same idea. This lesson plan follows the [concrete-pictorial-abstract (CRA) progression](https://www.monstermath.app/blog/cra-method-concrete-representational-abstract/), a sequence well-supported in math education research for building durable number sense rather than rote memorization. Each day builds on the one before it, so plan to spend roughly a week on this sequence - though some classes (and some individual students) will need more time at the concrete stage, and that's fine. ![Number Bonds lesson plan](https://prod.superblogcdn.com/site_cuid_cm6t228tz007prqzd9vdoqb9s/images/number-bonds-lesson-plan-1781867746609-compressed.webp) ## What you'll need for the week - Two-color counters or small blocks/buttons (about 20 per pair of students) - Paper plates or simple mats, one per pair (to act as a "whole" boundary) - Blank ten-frame printouts (a handful per student) - Crayons or markers in two colors - Whiteboard or chart paper - Index cards or small whiteboards for Day 5 number sentences ## Day 1 - Building Bonds with Counters _(Concrete ~45 min)_ **What you need:** Two-color counters (about 20 per pair), one paper plate or simple mat per pair. **Warm-up** _(~5 min)_ Count out 5 counters together as a class. Ask, "If I split these into two groups, what could that look like?" **Teach it** _(~10 min)_ - Split the 5 counters into 3 and 2 in front of the class, and say the bond aloud: "5 is 3 and 2." - Then split the same 5 a different way - 4 and 1 - and repeat. - Make the point explicit: the whole didn't change, only how we split it. **Practice together** _(~20 min)_ - Hand each pair their own 5 counters and a plate. Their job is to find every split they can, saying each one aloud using "\[whole\] is \[part\] and \[part\]" before moving to the next. - Once a pair finds all three splits of 5 (5+0, 4+1, 3+2), give them 8 counters and let them keep going (8+0, 7+1, 6+2, 5+3, 4+4). - Walk the room and listen for the sentence frame, not just the right split. **Neurodivergent tip:** Keep each "part" a single consistent color throughout - this helps dyscalculic students track groups visually rather than recounting. Cap the activity at two whole numbers (5, then 8); repetitive splitting loses ADHD attention fast once the novelty fades. **Check for understanding** _(~5-10 min)_ Can the student say the bond out loud in the "whole is part and part" frame without you modeling it first? ## Day 2 - Bond Hunt with a Target Number _(Concrete ~45 min)_ **What you need:** Same counters and plates from Day 1, plus number cards 1–10. **Warm-up** _(~5 min)_ Quick review: call out "5 is 3 and \_\_\_" and have students fill in the blank out loud as a class. **Teach it** _(~10 min)_ - Show a target whole (7) and one known part (4) on cards. - Count out 4 counters in one color, then add counters in a second color until the plate holds 7 total, saying "4 and 3 makes 7." - This flips yesterday's activity - instead of splitting freely, students are now solving for an unknown part. **Practice together** _(~20 min)_ - Run as a rotation: one partner sets a target and known part using cards, the other builds it with counters and says the bond aloud, then they swap roles. - Start with wholes from Day 1 (5, 8) before moving to new ones: try 7 (4+3, 6+1, 5+2), then 9 (5+4, 6+3, 7+2). **Neurodivergent tip:** For autistic students, write the routine as a 4-step reference card ("1. Count known part. 2. Add more. 3. Stop at whole. 4. Say it.") rather than relying on verbal instructions alone. **Check for understanding** _(~5-10 min)_ Given a whole and one part, can the student find the missing part with counters without recounting from scratch? ## Day 3 - Drawing Bonds and Ten-Frames _(Pictorial ~45 min)_ **What you need:** blank ten-frame printouts, crayons or markers in two colors. **Warm-up** _(~5 min)_ Show a completed ten-frame (6 filled, 4 empty) and ask the class to say the bond it shows. **Teach it** _(~10 min)_ - Draw a ten-frame on the board, color 6 boxes one color and 4 boxes another, and write "10 is 6 and 4" underneath. - This moves from physical counters to drawings, which forces students to represent quantity without rearranging it. **Practice together** _(~20 min)_ - Give each student a blank ten-frame and a whole number. They color two parts using two colors, then write the matching sentence below. - Have them trade with a partner and read each other's bonds aloud. Use 6 (4+2, 5+1, 3+3), 9 (6+3, 7+2, 5+4), and 10 (6+4, 8+2) across the sitting - three or four numbers is plenty. **Neurodivergent tip:** Keep the same two colors assigned to "first part" and "second part" all activity long - switching meaning between problems confuses dyscalculic students using color as their tracking cue. **Check for understanding** _(~5-10 min)_ Does the student fill the ten-frame in order (left to right, top row first) rather than scattering colors randomly? ## Day 4 - Bond Trees and Part-Whole Diagrams _(Pictorial ~45 min)_ **What you need:** whiteboard or paper, the [Number Bonds Visualizer](https://www.monstermath.app/teacher/tools/number-bonds/) if you have classroom display access. **Warm-up** _(~5 min)_ Draw a circle on the board and ask, "If this is 8, how could we split it into two parts?" **Teach it** _(~10 min)_ - Introduce the bond diagram: a circle for the whole on top, branching down to two smaller circles for the parts. - If you have a screen, project the Number Bonds Visualizer in Mode 1 ("Explore bonds") and let students call out splits as the tool displays them. **Practice together** _(~20 min)_ - Switch to Mode 2 ("Find the Missing Part") and have students predict the hidden part before you reveal it. (See the [Number Bonds Visualizer guide](https://www.monstermath.app/blog/what-are-number-bonds-teachers-guide-to-part-whole-thinking) for step-by-step instructions.) - No display? Draw the diagram by hand and have students copy it into notebooks for 8 (5+3, 6+2, 7+1), 9 (6+3, 5+4), and 10 (7+3, 6+4). **Neurodivergent tip:** Before using Mode 2, narrate the process aloud first - "I'll show a whole and one part, you guess the missing part, then I'll reveal" - so the unknown is in the answer, not the process. **Check for understanding** _(~5-10 min)_ Can the student read a bond diagram and state it as a sentence without help? ## Day 5 - From Pictures to Number Sentences _(Abstract · ~45 min)_ **What you need:** index cards or small whiteboards. **Warm-up** _(~5 min)_ Show yesterday's bond diagram for 8 (5 and 3) and ask, "How could we write this as a math sentence instead of a picture?" **Teach it** _(~10 min)_ - Draw a bond diagram like Day 4 - whole on top, parts below - and write the matching equation next to it: 8 = 5 + 3. - Ask what's the same (same numbers, same relationship) and different (no drawing, just symbols). **Practice together** _(~20 min)_ - Give students filled bond diagrams for 7 (4+3), 9 (6+3), and 10 (7+3) and have them write the matching equation for each. - Then flip it: give an equation (6 + 4 = 10) and have them sketch the bond diagram that matches it. Close by having one student narrate counters → diagram → equation out loud for a Day 1 number. **Neurodivergent tip:** Let students who need it keep counters on their desk even during this "abstract" day - moving to symbols doesn't mean removing access to concrete tools the moment they're introduced. **Check for understanding** _(~5-10 min)_ Given either a bond diagram or an equation, can the student produce the other without re-deriving it from scratch? ## Try it with the Number Bonds Visualizer The [free Number Bonds Visualizer](https://www.monstermath.app/teacher/tools/number-bonds/) pairs well with Days 4 and 5 above - it lets you display bond diagrams and missing-part puzzles without drawing them by hand, and switches between counter and symbol views to match wherever your class is in the CRA progression. ## FAQ ### Do I need to teach all 5 days in one week? No. This sequence is designed to be flexible. Some classes move through Days 1-2 in a single day; others need two or three days at the concrete stage before moving on. Use the quick check at the end of each day as your guide, not the calendar. ### What if a student is still struggling on Day 5? That's a sign to loop back to Day 3 or 4 rather than push forward. The CRA progression isn't a one-way staircase - moving back to pictures or concrete materials when abstract symbols aren't sticking is normal and expected, especially for students with dyscalculia. ### Can I use this for whole-class instruction and small groups? Yes. The activities are written for partner or small-group work, which scales down easily to a single small group during a math rotation, or up to whole-class with a shared display for Day 4's bond diagrams. --- This blog is powered by Superblog.
