One of the most important predictors and components of mathematical achievement has been found by Siegler and colleagues as the skill in placing numbers, including fractions, on a mental number line.
Siegler's theory of these mathematical developments aims to develop strategies to improve children's math learning.
Some of Siegler's studies are aimed at representing children's numbers to identify the learning of whole numbers, fractions and other arithmetic topics.
Therefore, these studies on the development of children's math skills are very useful in identifying why some children are more proficient than others and in identifying the strategies used by children to solve math problems.

Answer:
There is no chance that a child of one parent who carries CF gene is born having Cystic Fibrosis if the other parent does not carry the CF gene.
Explanation:
Second child born to Chloe’s mother and stepfather will have Cystic Fibrosis only if they inherit one CF gene from each parent. Since stepfather is not carrier of CF gene, development of the disease at child is not possible.
A person who has inherited one CF gene from his/her parent will be a CF gene carrier, but will never develop Cystic Fibrosis. However as he/she a carrier of the CF gene, they can pass it on to their own child.
John b Watson is a behaviorist. He believes that humans can
best learn when their actions are rewarded or punished. So it is B
Answer:
Unnecessary constraints
Explanation:
Unnecessary constraints is when people place a mental block to solving problem. They assume irrelevant information is causing distraction for a solving the problem at hand. Such is what Joan is facing.
