Guide
In Russian schools (Grades 1-4, "Mathematical information") children learn to tell true and false sentences apart, and from Grade 2 they work with the words "all", "every" and "there is". This is the base of all reasoning and proof later on.
A statement with "all" is true only if every single thing has been checked. One exception makes it false: that thing is called a counter-example. A statement with "there is" is true as soon as one such thing is found.
A false statement can be repaired: change "all" to "some" or change the feature. Ask the child not only to say "true" or "false" but to point at the picture and show why.
