Mmaki o tlisa dilofo di le 54 tse di thokwa le di le 68 tse ditshweu. Ke dilofo di le kae di le mmogo?

let's check your answers and complete the number lines!

a. Mmaki's loaves

• Problem: Mmaki brings 54 brown loaves and 68 white loaves. How many loaves are there in total?
• Calculation: $$54 + 68 = 122$$
• Your sum of 122 is correct.
• Number line for $54 + 68 = 122$:
  • Start at 54.
  • Add 60: $54 \xrightarrow{+60} 114$.
  • Add 8: $114 \xrightarrow{+8} 122$.
  • The total is 122.

Here's the correct visual representation for part a:

$$54 \xrightarrow{+60} 114 \xrightarrow{+8} 122$$

• Answer: Ke dilofo di le kae di le mmogo? $\boxed{122}$

b. Total on the number line

• This empty number line can be used to show the addition from part a.
• Number line for $54 + 68 = 122$ (using the number line up to 150):
  • Mark 54 on the number line.
  • Draw a jump of $+60$ from 54 to 114.
  • Draw a jump of $+8$ from 114 to 122.
  • Mark 122 as the final point.

Here's a visual representation for part b:

$$0 \quad \dots \quad 54 \xrightarrow{+60} 114 \xrightarrow{+8} 122 \quad \dots \quad 150$$
