A pre-school boy can go upstairs on alternate feet and has also started copying a circle. How many blocks should he be able to build a tower with, without toppling over?
Block Tower Milestone for Preschoolers
The abilities described, such as going upstairs on alternate feet and copying a circle, are typical developmental milestones for a child around 4 to 5 years old.
Assessing Block Building Skills
Developmental charts indicate that children in this age group are refining their fine motor skills and hand-eye coordination. This directly relates to their ability to stack objects.
- Gross Motor Skills: Walking upstairs using alternate feet shows developing coordination and balance.
- Fine Motor Skills: Successfully copying a circle demonstrates emerging visual-motor control and the ability to hold and manipulate objects precisely.
Expected Tower Height
Based on these developmental markers, a preschooler aged 4-5 years is generally expected to build a tower with a certain number of blocks before it becomes unstable.
Children around this age can typically stack approximately $8$ to $10$ blocks without the tower toppling over. Building a tower with $9$ blocks aligns perfectly with this developmental expectation.
Therefore, a pre-school boy exhibiting these skills should be able to build a tower with 9 blocks.
Important Questions from Growth and Development
Which one of the following figures should a five year old developmentally normal child be able to draw?
Till what age should corrected age be used (rather than chronological age) for the development assessment of babies born preterm?
A 12 year old child presents with delayed puberty and delayed bone age. His growth records reveal that he was growing normally till 1 year of age, after which both his height and weight fell to below the third centile for age. Subsequently, he continued to grow below the third centile with normal height velocity. What is the most likely diagnosis?
Which of the following developmental skills will you expect a child to have acquired by 9 months?
