## 21) Bonds

Five Plus Bonds: Building a Wall

### Mathematics

Develop the concept of 6,7,8 and 9 as made of 5 plus another part.

### Language

• five plus bond: a bond of five and one other part makes the whole.
• equals as “is”

## Differentiation

### A little easier

##### Section two: ten frames

Support recall by using fingers to develop five plus fluency. Explicitly relate each hand to the relevant row of counters on the ten frame.

Finger subitising to support 5 plus bonds shown with right hand dominance. The fingers on the right hand change each time.

Students with fine motor difficulties may not be able to separate fingers easily or use their thumb to hold other fingers. Do not insist these students use a representation that is difficult for them. Consult their occupational therapist for advice.

##### Part-Part-Whole diagrams

These part-part-whole diagrams  can be stuck to the top of student’s desk, as a desk visual, until students are fluent recalling these facts. Students with memory or processing difficulties can benefit from having visuals as permanent prompts.

##### Part-Part-Whole diagrams

• Cover different numbers to practice recall.
• When students are fluent identifying missing numbers in counting order cut the strip into single cards. Randomise the order of the diagrams and practise recall covering different numbers.

### A little harder

##### Identifying missing numbers

In pairs, students to order their blocks on the desk as per the activity board. Instruct one student to close their eyes, whilst their partner removes one block from each part-part-whole build. The other student has to identify which blocks were removed.

Develop fluency by moving the arrangements out of ascending order. Then identify what’s missing.

An activity for individual students.

The teacher models filling a ten frame orientated horizontally, from left to right, top row first to make 6,7,8,9. Draw attention to the number of spaces left to fill the frame relating this to bonds of 10.

The teacher calls out 6,7,8,9 in random order. Students fill their frame with this amount of counters. Students do NOT clear the frame of counters after making each number. Instead students alter the number of counters on the frame to make the new quantity. Doing this helps students learn about the comparative size of numbers. For example, 8 is 2 greater than 6.

##### How many more to ten?

In pairs students calculate how many more to make ten.

• Students place an empty ten frame Bond Block in front of them.
• Student One picks up a 1,2,3 or 4 Bond Block in random order.
• Student Two has to make the number that joins with this to make ten as a five plus fact, placing their blocks on the empty ten frame block.
• Student One checks the answer by placing their block in the empty space to build ten.
• Swap roles

### Progression

In the next activity students develop fluency with five plus bonds, representing them in a variety of ways, when they are presented in random order. Go to
