Thank you to Daniel from Englefield Green Infant School and Daina and Emma from Kelso State School for their solutions to the Number Lines problem. Daniel said:

Leah's first secret jump was $4$, $4+5=9$
Leah's second secret jump was $4$, $6+4=10$
Tom's first jump landed at $5$, $3+2=5$
Tom's first secret jump was $2$, $2+6=8$
